5 out of 5 eggsGreat Card

Pros: This card is fast amd i love the water or air cooled option. Build quality is excellent and it tears apart all games at 1080p. once i have my triple monitor setup hooked back up i will review again but for right now this thing is a beast.

Cons: Barbs not included. I think for a card of this quality Asus should have included even some cheap barb fittings. (2 90° fittings with the ROG logo would have been sweet.)

Other Thoughts: Intel Core i7 4790K 4.8ghz / 32gb GSkill 2400 / Asus Maximus Gene VII / Asus 780 Poseidon / 2x Crucial 512GB 100MX

5 out of 5 eggsNice bang for buck

Pros: Water cooled with factory warranty, ease of overclocking, and downright amazing with 2 in SLI mode.

I have two of these in SLI for a graphics rendering/ gaming rig and the speed of them with a mild overclock just makes me giggle. I am using the factory preset overclock settings.

Cons: Not really a con but having to custom build the water cooling system

5 out of 5 eggsASUS ROG Poseidon GTX 780 - Excellent build quality, appearance, and built-in water cooling... for a premium

Pros: Very quiet and cool, even on air, at normal to mid-range loads. It has water cooling ability built in, which will cause temperatures and noise levels to drop greatly if used, especially at full loads, plus you don't have to spend money on an aftermarket water block or risk voiding your warranty.

Extremely well-built, with a hefty back-plate to keep it rigid and help with component cooling.

Easily outclasses my GTX 670 setup in the two benchmarks I tried (Unigine Valley and 3DMark Firestrike demo), scoring almost 50% higher in some areas.
See Other Thoughts below for details and test results.

Attractive appearance, with a slowly pulsating red ROG logo on the top edge.

Green LEDs by auxiliary power sockets (8-pin and 6-pin) which turn red if your PCI-e cable is not plugged in correctly (a nice touch - the ASUS DirectCu II GTX 670 also has these).

Streaming tool in the GPU Tweak software (I have not tried this yet).

Came with free Watchdogs game coupon. Although my coupon had officially expired I was still able to redeem it and download the game.

Stably powered in SLI by my 850W Seasonic PSU. Performed flawlessly in Kombustor stress testing and elsewhere, except for one glitch in one benchmark, which may be a driver issue (see next section).

Cons: There was a glitch when running the Unigine Valley benchmark, where occasional white flashes appeared on the screen - like lightning following the ground, as if it was trying, but failing, to paint a flat section of the landscape (not sure if this is a shader problem).
Apparently other people have noticed this with 700 series cards, so perhaps it is a driver issue. Since it occurred with both of the Poseidons I tested, and they are unlikely to both be faulty, I hope this is the case. I never noticed it in the 3DMark tests, Kombustor, or any games.

Price - All other GTX 780s cost less then the Poseidon (at time of writing), and some have faster clocks from the factory. Also, you could buy a GTX 780 Ti for less than $100 extra, although it might be of lesser build quality or cooling performance (even on air). You pay a premium for the Poseidon's extra features, and maybe the ROG branding.

Other Thoughts: It's quite a hefty, long card - check your case specs to see if it will fit, and make sure you screw it down securely at the case slot to avoid motherboard strain. Also be sure to plug in the auxiliary power connector to your motherboard if needed for running SLI. You'll definitely need it for more than 2-way.

It's a shame the Poseidon doesn't come (as yet) in a Ti edition, but I think it was already in development before the 780 Ti was announced by nVidia.

I was impressed by its performance compared to a fairly high end card from the previous generation (GTX 670, which performs close to a reference GTX 680 in some situations).
Below are the results of the benchmark comparisons I mentioned earlier.
[NOTE: I have 2 ASUS DirectCU II GTX 670s and tested them against 2 ASUS ROG Poseidon GTX 780s in both single and SLI mode. Resolution was set to 1920x1080, native for my monitor]

In SLI, the Poseidon came in the top 3% of recorded scores for the 3DMark Firestrike demo. This was in a rig with an i5-3570K CPU, mildly overclocked to 4.2 GHz on a Gigabyte GA-77X-UD5H mobo, with 16GB of Mushkin Blackline 1600 RAM. The graphics cards were not overclocked, and the Poseidons were not water cooled (that will come later, as will a more powerful CPU/mobo combination).

Firestrike demo scores:
GTX 780 (1) 8224 - better than 83% of all results
GTX 670 (1) 5850 - better than 57% of all results

GTX 780 (SLI) 12532 - better than 97% of all results
GTX 670 (SLI) 8617 - better than 83% of all results


Unigine Valley scores (Extreme HD preset, 8xAA):
GTX 780 (1) - 62.6 FPS, Score 2620
GTX 670 (1) - 42.6 FPS, Score 1782

GTX 780 (SLI) 102 FPS, Score 4266
GTX 670 (SLI) 77.3 FPS, Score 3233

Noise levels between the two models were roughly the same across all loads and. quiet up to mid-loads, with temperatures up to high 70's C in the stressful benchmark sections. Even at high loads, fan noise was not objectionable and there was no whining.

CONCLUSION: In my opinion, this card only makes sense to buy if you intend to water cool it, otherwise you are wasting money on a feature that will never be used. On the other hand, assuming you have that intent, you get a factory installed, integrated water block (saving you a lot of hassle and possible warranty issues), and potentially the ability to overclock better than its lower priced competition. Plus, it will look very nice in an appropriately-themed build, especially in an ASUS ROG rig.
Because of its build quality, features, and attractive design, and despite the one glitch I encountered -- which I attribute for now to a driver issue -- I believe the Poseidon is worthy of a 5-egg rating.

3 out of 5 eggscompatibility issue....

Pros: Looks well made and is very nice.

Cons: How does this card not work with the Rampage IV Black Edition motherboard?? I was guessing since both are ROG endorsed that there would be no issues, but this graphics card is not compatible with rampage IV apparently. I called Asus , and they didn't quite give me a straight answer to how to find out which graphics cards would be compatible with this board. I can find a GPU compatibility list anywhere for the motherboard.

Other Thoughts: I docked 2 eggs because of compatibility issues , not really on neweggs end , but also maybe somewhere it should be noted that it doesn't work with the rampage board.

5 out of 5 eggs

Pros: The build quality of this card is very good the card itself looks like a work of art, very pleasing to the eye. the back plate is very nice as cards keep getting bigger and heatsinks have to get larger it's going to be more and more of an issue with cards bending from the weight. I did a custom Waterloo in my system and benchmark everything to make sure all my hardware was up to par, I ran this graphics card through 3d benchmark 3 times in a row with ambient room temperature being at 85 Fahrenheit the temperatures stayed cool well within safe margins on the fans only and they were at stock speeds. Then when I put my water loop in I over clocked it to the exact specs of the 780 ti to my surprise the overclock stocks then I ran the 3d benchmark with no problems and, Temps on the GPU were well within safety margins

Cons: I have only one complaint about this card the water block itself is iodized aluminum which could become a problem in the future with my water loop please read other thoughts

5 out of 5 eggsNice cards!

Pros: It is fast and it has options for air and water cooling.

Cons: No cons.

Other Thoughts: I put 2 of these in SLI and I couldn't be happier. I was worried that if I didn't go ahead and get 2 cards that I would be upset when I can't them later. These are the best cards I have ever owned.

4 out of 5 eggsMmmm, red matches my motherboard...

Pros: You should be able to get a 180 to 200 MHz core overclock on this card easily on liquid. Memory should overclock 100 MHz or more. No need to purchase a waterblock if you're planning to liquid cool. Cheaper than a GTX 780 Ti (Is that a pro?). Mine worked out of the box without issues, unlike many AMD cards I've had to RMA lately due to bad luck.

Cons: Even with the overclock, you're not going to get near GTX 780 Ti speeds; you'll probably be more around the original Titan in benchmarks. GPU Tweak utility can overvolt, but it has to be manually set again at reboot; overclocks will stay after a reboot if you select the proper option. GPU Tweak will crash on Windows Vista. (Yes, the little operating system that everyone hates, but I have a few games still to complete that don't run well on Windows 7.) Still more expensive than a reference GTX 780. Liquid cooling helps reduce the temperature, but after half an hour of testing, it still comes in at a warm 56 degrees Celsius. Card is hot to touch even with liquid cooling due to minimal liquid contact with VRMs and memory, which seem to be air cooled. Although I'm unable to verify, some sites state the liquid channel is aluminum which may cause corrosion in mixed metal systems. The diameter of the liquid cooling channel also seems small when you look down into it, which could restrict coolant flow.

Other Thoughts: I was looking for a liquid cooling solution to replace some dying GTX 570 cards I had. Would have loved to get a GTX 780 Ti, but with those being a hundred more than this card, and double that for a waterblock, it wasn't in the budget. Benchmarks show the card, when overclocked, to be slightly faster than two GTX 570 cards in SLI. Heaven 4.0 with max settings at 1920x1200 is hitting 57 fps; the 570 cards were getting around 52 fps. In comparison, a single GTX 670 is getting around 36 fps, or about 64 fps in SLI on my system. It could be better, but about what I expected for the price.

5 out of 5 eggs2x the pleasure

Pros: Well built and allows me to run the Asus CU II on the bottom and run this one on H2O and air. I'm running 4 monitors 3 23" 1080p Dells at 5760x1080 and a Asus 27" 2560x1440. Not at the same time with surround. On the 27" BF4 gets 120-130 fps on ultra. Not tested my race Sims yet but the surround should get about the same. Very beastly lol

Cons: None

5 out of 5 eggsWell Worth the Purchase

Pros: This thing is beautiful to look at. The front glowing ROG red led looks amazing. just looks complete sitting on my asus maximus v extreme. The water block combo is nice to have. going to add it to my custom water loop soon. runs really cool just on air. Runs all my games on ultra high details maxed out on 1920x1080. League of legend, elder scrolls online, mass effect 3, all look Amazing! I decided to trade out with my XFX 7970 which had horribles screen tearing, which seemed to be getting worse with each new driver update. was going to go with the new Radeon R290x . But they are never in stock and most of the time now pricier than a 780! and not to mention everyone says runs hott as hell! I was a total AMD fan boy. Nvidea has made me a believer.

Cons: Honey moon stage to soon to tell!
