I've finally had enough of my slow-as-molasses shop computer and I'm looking at rebuilding it with some slightly newer parts. I found and bought another NF7-S 2.0 motherboard (why did I ever sell mine off?) and some RAM but I need a AGP 8x video card, nothing special. I was thinking something along the performance lines of a 6800GT, but I think I want an older Radeon card this time; I'm not sure what to get. What is a decent ATI equivalent? Preferably 256MB RAM... thanks in advance!
