Hello I recently made the decision that I want to upgrade my graphics card because I'm tired of "meeting the reccomended settings" then jumping into the game to find I have to turn things near to minimum most of the time, medium if I'm lucky. Anyway, I currently have an Nvidia GeForce 8600 GT, and after a lot of research I decided I wanted to get the Nvidia GTX 460 as my upgrade, though after I set my mind on it I noticed in a comparison, my old card is PCI-e v1.0, and the GTX 460 is v2.0. My question is, how much reduced performance will I be getting from using the GTX in my system? would it be so much so that I'd be better off getting a 1.0 card? Also, if I put the GTX 460 in at the same time as the 8600 GT (I have two PCI-e v1.0 slots) would I gain any performance from that being that I can't SLI them? (my mobo does support SLI though, so would getting another 8600 GT and running them in SLI be a better solution overall?) I was hoping to run the new Sonic Generations game (with good performance), but can anyone help me with upgrading my graphics card please?
