Looks like the 5750 either ties or loses to the GTS250. Once you throw AA on however the 5750 either ties or wins. I'd argue that they are close enough you should buy based on price, package, power use, etc.
How little Maz? I thought the GTS250, 4850, and 5750 were all around the same performance?
Yes all those 3 cards basically have the same performance.
I was going to post the link which you later posted(Tom's hardware review),in some games GTS 250 wins and in some others HD 5750,but overall the performance is pretty much the same
