I usualy tend to buy this segment of graphic cards, but what are the differences between them. I have seen a lot of reviews about them both and from the number and cost all can say directly the 5770 is better. I was thinking which is the best third party and is it worth to spend more money on 5770? or better sticking to 5750? (in fact i want more knowledge about these two cards, not that i am going to buy them whith the current system) Thank you!
