I am going to build a dual core box and I have a budget of $500. (wife set limit)
Currently I run XP2400 w/1.25megs of ram with ATI 9800 pro and ATA133 200gig HD.
Now for $500 I can build a Intel Pentium D940 3.2 ghz w/ 2gigs of DDR2 533mhz memory with a fast SATA-300 16meg cache 250gig hard drive. The only thing is that I must keep my old video card

I figure I can always upgrade mother board and video card when I have the funds down the road(when the wife lets me)
I have read that FS9 is more CPU and memory intensive than GPU demanding. How true is this?
