I got the 5770 to replace a dying NVIDIA 8800GTX. This card cost me about 1/3 of what the 8800GTX cost me when it first came out. It is 2/3 the length of the 8800GTX, uses 20% less power and runs so much cooler, I am amazed.

I'm sure people will want me to tell them how it works with various games. I'm afraid I can't since I don't use them. I am, however, an avid user of Microsoft Flight Simulator X and can tell you that this card is superior in every way to the 8800GTX. Scenery textures are crisp with no blurries, FPS run 10% higher or more and light bloom looks a lot better.

This isn't the biggest and baddest card out there, but it amply fills my needs. I had seen a number of forum posts about people having problems with Windows 7 64 bit, but installing the latest drivers went flawlessly. My only complaint is that the Catalyst software can be a bit obscure about how to change certain settings, but I'll get used to it.

I am running a machine with windows 7, an AMD phenom II quad core processor, and 8 gigs of Ram. I like to run my games at 1920x1080 wide screen. I can run games like Mass effect 2 or mirrors edge at full settings with no slowdown issues. Crysis also runs very well at this resolution with everything turned up and suffers only a slight frame rate drop. So in short you can run most games at very high resolution with everything turned up and suffer no, or slight frame rate drops.

When I purchased this card I was very happy and I have enjoyed a very good run with it. This is still a really nice card and I have enjoyed it for the time I have had it. But the future is here. It can no longer play some of the newer games at optimal performances as I stated in the past. Some newer graphically rich games such as the witcher 2 can give it a run for its money even at the lower settings. This new review is not to discourage you from looking at this card... Read more

I bought this video card to play World of Warcraft. It is a huge improvement from the last one, I'm able to play in Ultra mode with 46 fps. No more slow motion when casting spells.

For the price, it's a very nice video card for this kind of games. If you want to play more video-demanding games, you should check another one.
