Hi all... So I just got a new motherboard, it's an ASUS P5Q3 Standard. Problem is that it's Crossfire ready, but I have an nVidia 9800GT (EVGA brand) 512MB DDR3 video now (SLI ready of course). So I was going to try craigslist and see if anyone had the opposite problem as me. I haven't had an ATI card since my Radeon 7200, so can someone tell me which Crossfire card(s) are comparable to mine that would make a nice trade?
