Hey all, I know this is prob asked 24/7, but I need some help choosing a new GPU. I deff wanna stay with ATI, but Im not sure what is best suited for my use. I mostly game at 1680 x 1050. What I have in mind is a HD 4890, HD 4850x2(1Gb), or lastly the HD 4870(1Gb). The reason for the 4870 is how low prices are getting on those. I just want to get the best performance and not kill my wallet. So what do you all think is the best of the 3. Any and all opinions are appreciated.
