I just ordered a 5870. I am going to be getting rid of my 4870 x2 quadfire as it has never panned out performance wise. I had a couple of questions about the 5870. I know that it performs better with the x58 based systems. I will upgrade to that later. For now I am running a Q9650 @ 4GHz. Will this bottleneck this card at 1920x1200 resolutions?
