4 out of 5 eggsGood, solid, and stable

Pros: I have a WinXP OS running 2 of these cards in Crossfire. I'll eventually upgrade to Win7 to experience the DirectX 11 over-hype, but in the meantime I'm loving every minute! It's my first dual-vid setup, and despite the fact that I've had Nvidia cards on my past 3 systems, a pair of these babies rock!

I'm running WOW at 1600x1200, 8x Aniso, 4x AA on a Q9650 and I'm maxing out at my monitor's refresh rate of 60fps. COD4:MW2 was maxing out at 1600x1200, 4x Aniso, 4x AA 45-55fps.

I'm mostly interested in Diamond's reliability. No overheating issues, no flickering, no banding, no stuttering.

Card's short length, relative to older models, is very welcome in my already-tight Antec Nine Hundred case.

Solid card all around.

Cons: I've always admired ATI's dedication to driver completeness. My one and only gripe is the REQUIREMENT to install Microsoft's .NET framework to benefit from the latest ATI video drivers.

It confounds me as to why I have to install enterprise software BEFORE I can get full functionality of ATI's Catalyst drivers. In fact, on my past 3 systems, this pain alone was actually strong enough to push me over the edge when I'm comparing Nvidia and ATI cards of the same price and performance. I mean, why bother with ATI's video card that requires the .NET framework when Nvidia saves you the headache of having to install a piece of software that most home users don't even know nothing about?

Heck, do you know what the benefits are of installing Microsoft .NET framework on your computer? If you're like most home users or casual-to-hardcore gamers for whom this video card is targeted to, then you're most likely reply is:

".NET? Huh? What's that?"

Other Thoughts: ATI Catalyst drivers, as of ver. 10.3 , do not have any means to visually indicate Crossfire performance. Aside from seeing, first-hand, noticeable performance increases via synthetic tests or gaming fps measurements, you'll never know if your Crossfire-configured cards are running at their optimum.

With Nvidia video drivers, Nvidia is kind enough to include some kind of visual performance metric to notify you of SLI activity and load. ATI, on the other hand, leaves you in the dust in this category and makes you wonder what activity and load their GPUs are put under.

It's not that bad, but I still want to know if my ATI GPUs are doing the best that they could. Just knowing that I'm +20FPS above a single-card setup is not enough. I want to know if the ATI GPU is maxing out, and ATI can start by showing me GPU load.

3 out of 5 eggsVoltage / power controller doesn't work so not good HTPC use

Pros: * Friendly technical support.
* Fan is quiet upto exactly 40% with card two feet away from my ears.
* Absolute idle power (0% vs. 2D Windows usage) and load power (gaming, furmark, etc) is equivalent to working cards.

Cons: * Power controller's voltage output is stuck, and does not AMD "Power Play" with load.
* For UVD video playback, my quick measurements showed increase of about 10-15 WDC vs. a card with load-varying voltage (or about 12 to 19 WAC with 80% power supply efficiency).

Other Thoughts: I expect video boards to not only have low power idle, but low power when playing videos. When doing nothing and at load, this card is OK. But UVD load or video playback is in the middle. UVD frequency is in the middle of the 5770s operating range at 400 MHz, the typical 1080p % load is low to middling (10-30%), and the GPU voltage should start at 0.95V. But this card design is stuck at about 1.17-1.18V. So power consumption was noticably worse than the other 5770 I compared with.

Unfortunately I only remember only one review site, the german HT4U, which ever measures GPU voltage as part of their reviews. This card's vendor ID is 0x1787: "HIS, Club3D, Jetway, Powercolor, Triplex and others". So look up reviews of the 5770 cards with this same design. I wasn't interested in 5750s, but the the 5750 review seems to show different designs. So the 5750s with this cooler may not exhibit the same symptoms.

A 03/10 BIOS didn't fix things, but hopefully a later BIOS will.

4 out of 5 eggsNot bad

Pros: Pretty sweet card. scored great on Win 7, definatley best bang for the buck.

Cons: I'm haveing driver issues with it. Done Bios, chipset and all other driver updates but I can't get the 10.2 driver installed for video. Catalyst went fine, but I read that these new cards and updates will do up to 120Hz refresh rates which is what my monitor does.

Other Thoughts: Like I said said, Best Bang for the Buck. The driver issue must be user error.

5 out of 5 eggsissue with mouse

Pros: Small in size but very nice card!

Cons: Issue with Mouse pointer increasing in Size! I fixed it by turning trails on in mouse setting and turned it to low lol.

Other Thoughts: The Quality of the card is very good and do not have any issues with it. I'm running 2 monitors and works great watching movies and play Warhammer.
Had small issue and newegg was very helpful in fixing them I'm happy to give them repeat business

5 out of 5 eggsExcellent Card for the Money

Pros: This is just a solid card for the money for anyone wanting DirectX 11. You crossfire this and i guess it really fly's. This is my first diamond card. I always had EVGA but i am very happy with this so far.

Cons: none so far.

5 out of 5 eggsI'm happy with it

Pros: ASUS finally did something right again. I have been using these cards for years, and have always bought the All-in-Wonder series, but I was disappointed with the HD version, so I bought a "dedicated" video bd this time. I am really pleased with this card and its performance (7.9 in Win7).

Cons: I accidentally touched the fan and it immediately jammed. I shutdown the system and slowly backed it up, and the blade sprang back to position. Thanks to the "inappropiate word for supreme diety omitted" for flexible plastics.

Other Thoughts: This is part of my new Win7 gaming system. i7 920 overclocked to 3.4GHz mounted on a ASUS P6T with 6GB of Corsair 1600MHz RAM and two Seagate HD's in raid 0. Probably the fastest rig I've ever owned.

5 out of 5 eggsHD 5770 Is Awsome

Pros: Great Card, to test ran 1080p Bluray to one Monitor, WOW on another, and normal browsing and surfing on the last.

Cons: Power specs on the card are a little off, you will need at least a 550 watt PS to run this card at it potential. I had a 550 with 3 Hard Drives and it wouldnt run smooth in Dual Monitor, Upgraded PS and then it was Excellent.

Other Thoughts: GA-MA785GM-US2H, 800 WATT PS, AMD Athlon 64 X2 6000+ OC to 3.4, 8GB DDR2 6400 CAS 4 RAM, 3 WD 1TB HD, Bluray DVD Drive, CD/DVD Burner

5 out of 5 eggsNice cards

Pros: Great cards. I have two of them. Actually score about 100 points less on 3dmark06 then two BFG tech GTX275's
I feel sorry for anyone who tried to save a buck and bought the powercolor ones with the same fans.

Cons: I feel sorry for anyone who tried to save a buck and bought the powercolor ones with the same fans. Because these ARE NOT THE SAME CARDS!! There are NO issues with these cards on Three systems that I own.
No matter which I put them on they work Phenomenal. All the issues people are talking about with ALL of the 5770s DO NOT HAPPEN WITH DIAMOND Cards. When will people learn that Diamond Always makes a superior ATI card then everyone. They dont get the credit they deserve because their logos usually are not as Cool looking as the others. But they dont need to be. Those who use diamond products will not use anything else. I had two 2900s on water and they have been kicked water dropped on them. clanged together in boxes. Put in 6 systems. had the heatsinks pulled off and reset so many times I cant count. And now one is sitting on my floor hooked to a corsair nautilus and I use it as a tester card. IT WILL NOT DIE!!! AND ITS BEEN ABUSED TO H#ll AND BACK!

5 out of 5 eggsGood solid HD5770 card

Pros: This is basically the PowerColor 1GB card that everyone was raving about with a Diamond logo - same PCB and everything. Great card.

Cons: Can get noisy if you put the fan much above 40%

Other Thoughts: I bought this for use this in a mid-high end HTPC, where the main benefits have been (ironically) work related - screen refresh when I did remote desktop on my 1080p display used to c-r-a-w-l on my motherboard's built-in Intel GMA4500HD graphics, now they are quite snappy. All the things I bought the card for (bistream audio for Blu-Ray and the ability to do mid-level gaming) work great but are a bonus by comparision.

Using with Win7 x64, followed the advice of others on here and downloaded the latest drivers from ATI - has been working without a hitch.

5 out of 5 eggsFirst reviewer! Ahhhh.......

Pros: - Fast as blazes for the price; it's basically 1/2 of a HD 5870 chip.
- Passmark 3D = 1696; makes my admittedly old games (HL2 series, Halo series, Quake Wars, etc) buttery smooth, even at max quality, AAx4, AFx4, 1920X1080. No more jittery, blocky games!
- 1 GB memory for large screens.
- Diamond name brand - was a quality outfit in the past, haven't heard much recently. Card was well constructed, no kludges or cheap bits.
- Eyefinity? >drool<.....

Cons: - Had to wait for a deal to meet my sub-150 price point, but it happens occasionally....
- This card does NOT exhaust to the outside the case, so plan your ventilation accordingly. My system was 36C (from mobo sensor) without, and 40C with this card installed.
- ATI Stream/OpenCL (ie, GPU processing) support is very spotty still - a Folding@Home link is installed when you install the Catalyst driver, but the application doesn't yet work with HD 5000 series GPUs!

Other Thoughts: All I had to do was wait a bit, and I got my price! Shipped free in 5 days flat. Really glad I didn't pull the trigger on that 250 GTS before this came up. Newegg rules, of course!
