ATI is making some great new GPUs at wicked price points. They are not the rock stars their $800 dollar+, top of the line cards are but for starting at $160, they are pretty wicked at that price point..
I had trouble finding a review that actually tested more than playing a video game or two but Tom's hardware is always good for the latest hardware reviews and providing the bad with the good.
ATI Radeon HD5770 and 5750 Caveat: I haven't seriously compared cards in a couple of yyears, I just happened to see the specs on these somewhere and was surprised by the price point.
