So I'm building a new system with an E8400 & PQ5 Pro mobo, and I wanted to see what you guys thought was a better plan. Should I buy a 4870 now and in another year or two if I feel its too slow for me, get another for cross-fire (from what I've read I don't think 8x/8x really bottlenecks the 4870s) or do I just buy a GTX 260 now and then get a new card completely when the time comes. I only hesitate on the crossfire option because I have favored nvidia in the past, mostly due to the companies offering the cards, and the fact that I would probably need to get a bigger power supply than I was planning on (520HX). I realize it will more or less come down to personal preference on when I think I need to upgrade, but I would like to go 1 1/2 - 2 years. Thanks.
