I've just recently bought one of these cards as I was keen to check out the new Radeon 7000 series cards, and this one is really good value. The card itself is well made, with a really good cooling fan, which runs pretty quietly, even when playing games.
So far I've tried quite a few games at in Full HD 1080p res and they look terrific, Wolfenstein, Call of Duty Black Ops, Splinter Cell Conviction, Batman Arkham City all run really well, and pretty smoothly, with only one or two dips in frame rates now and then, so you might turn down the anti-aliasing settings. Graphically games look even better with the 7750, and its even more powerful card than my old 6770 card. Another really good thing is the card doesn't require a pci-express power connector so its low on power consumption.
So the new Radeon 7750 is a great card, and it can play pretty much all the games you can throw at it. So for the money its well worth it!
