EVGA 04G-P4-3687-KR GeForce GTX 680 FTW+ w/Backplate 4GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

Pros: Very Good GPU. Plays anything on MAX settings.
On Crysis 3 you can run ultra with a bit of AA
If you're trying to get a card that runs max with a the 500-600 Dollar mark. Get this one or the GTX 680 classified.

Cons: Really HUGE. Make sure you have enough room in your case or it might not fit. It's not a problem with me because i have more then enough room for another one of these bad boys.

Other Thoughts: Make sure you have at least a 600 watt power supply.

Pros: I've upgraded from two 1GB ATI Radeon HD 5870's in crossfire, to two new EVGA GTX 680 4GB FTW edition 4GB cards in SLI. My system is an x58 running a liquid cooled gulftown i7 980x 6-core processor clocked to 4.2 GHz. There's an 875 watt PSU and 24GB of Kingston HyperX 1600 RAM (triple channel). It's a capable machine for a MicroATX PC. I game at 1080p on a 2ms Samsung monitor.

So I finally went green and switched to Nvidia. The Radeon HD5870's were OEM and I was actually very content with their performance over a decent span of time. However, AMD has SERIOUS driver issues that make a person want to rip their hair out... I could not take the updates anymore. Also, with several recent games such as Skyrim and a few other titles, the limited video memory was making play quality unacceptable.

There are many perks to the EVGA GTX 680's running in SLI. I was blown away with the quality difference in a great number of games. The Witcher 2, Skyrim, Battlefield 3, Arkham City, and Metro 2033 were being absolutely man-handled by the 680's. All games were played at MAX settings (or even higher through tweaks/mods). I had the Witcher 2 maxed out AND had ubersampling turned ON and these cards still ran the game very smooth, locked at 60 FPS.

My idle temps were ~34 C and ~38 C which is very nice. The cards are constructed and fashioned well. They are smaller than I had imagined. They do not generate noise. They are INDEED dual slot and no larger! (even with the backplate) The cards have a nice feature in the design of the heatsink shroud: the cards are slightly recessed at the fan end of the enclosure and this allows air to enter a bit easier if your PC case is compact.

EVGA customer support is incredible. They are good people. It is great that these cards come with a 3 year warranty too.

Cons: Arkham City had occasional stutters, but they were not offensive or disruptive and I don't believe the GPU's were to blame.
LA Noire ran noticeably better but there was just something off about the experience... the camera panned in awkward ways and it gave the illusion of lag.
Nvidia's new Vsync tech seems better left unused.
If you enter the Nvidia settings and set the cards for "maximum performance" instead of "adaptive" your cards will not save any energy and will stay at max video clock frequency state - potentially causing heat issues. My temps rose from ~34 C and ~38 C all the way up to ~46 C and ~54 C.

And the obvious... The cost is insane. It is the best single GPU card out right now though to be fair.

Other Thoughts: The new Metro game comes out in two weeks or so. Metro Last Light. I wish that I already had the game now so that I could really see what these 680's were fully capable of. I will try to update this review when I test the cards running on the new Metro game.

Pros: Incredibly Fast
Internal Fan Cools Very Well
Runs all games at max settings with zero lag

Cons: Too big for my case

Pros: I replaced my GTS 250 with this GTX680. I can't say enough good things about it. Easy install and easy set up. I bought it specifically to run Planetside 2 on ultra settings and its amazing. I am getting from 60-120fps in large to small fights respectively. The GPU runs very cool too it maintained 27c for 4 hours of PS2 play. I plan on adding another.

Cons: I have none.

Other Thoughts: Just be sure you have big enough PSU. I had an ATX 600w but only 28 amps. This GPU needs at-least 550w 38amps on a 12v rail. I ended up upgrading my PSU to a Cooler Master 800w Silent Pro Gold.

Pros: Amazingly fast, plays all games on ultra settings full 1080 p no problem, like battlefield 3, diablo 3, starcraft 2 heart of swarm! Usually my FPS is constantly over 100 even if there is intense action going on in game! I don't even see the need to run it in SLI!

Cons: Really expensive, a a classified 680 came out that is better than this one.

Pros: -Sturdy
-Beautiful renders
-You can throw anything on the market at it on the highest settings - the 680 GTX FTW will absolutely destroy it

Cons: None really.

Other Thoughts: Worth it. I would certainly recommend this card - especially for gamers.

Pros: Just a great video card. Easy installation with lots of power. Runs cool and quiet! Probably will never test the limits of this card but plan on it being a great crad for years to come!

Cons: None

Other Thoughts: My build:
Thermaltake Level 10 GT
ASUS Maximus V Extreme LGA 1155
EVGA GeForce GTX 680 4GB
CORSAIR AX860i
Intel i7 3770k 3.5Ghz
Samsung 84 Pro SSD (x2)
G.Skill Ripjaws Z series 32GB memory
WD 1TB
ASUS Blu-ray Drive
Windows 8 64Bit Professional
Noctua NH-D14 CPU cooler

Pros: This card has not gotten above 55C since I installed it. I installed the optional Precision X software which has fan control even though I do not plan on overclocking the card. It's already overclocked anyway with automatic boost. Using the HDMI straight to a 65 inch TV. Games and everything else looks noticeably different compared to the 9800GTX+ in SLI that was there before. Thinking about getting another one ... but it handles every game so easily. I like the reference design which takes warm air from the case and blows it out the back.

Cons: None - maybe cost? But you have to pay for the best.

Other Thoughts: Intel X58 MB
Core i7 920
GTX680 FTW+
2 600GB Raptor Drives
Plenty of speed adjustable fans

Pros: Powerful, pretty quiet, low draw on PSU.

Great as a single GPU, good results with my i73770k on all major Benchmarks.

Cons: Price...

Pros: * Run 2560x1440 on main monitor, 1920x1200 on secondary. Everything I have runs full quality.
* Fairly Quiet

Cons: * Price compared to performance difference. There are better deals out there if you don't demand full quality at 1440p+ Res.

Other Thoughts: * Skyrim loaded up with mods like HD Textures, Lush Grass, etc run 40 FPS+ runs about 1.8gb video memory.
* Crysis 3 runs full quality 30 FPS+
* Bioshock Infinite runs full quality 40 FPS+ (with latest drivers).
* Battlefield 3 runs full quality 40 FPS+
* Most video memory I've seen used is BF3 after about an hour. Game obviously has a memory leak but I've seen it climb to 2.2 gigs+ (starts at about 1.4)

TIPS:
* Don't buy the extended warranty, when you register with EVGA it provides several better warranty options you can purchase then.
* Download EVGA OC Scanner so you can run NV-Z, especially if you run a second monitor.
* Glad I bought a 4gb card with games already pushing it today at my high res.
