I agree with WarriorII. I'd buy a new DDR board. I could'nt believe the difference in speed when I went from a PIII system @ 1000mhz running PC133 Ram, to a 1200 mhz AMD system with DDR. And this was with an Ali Majic chipset (Asus A7A 266) which pretty much suck's. My boot time alone was almost cutt in half. Game's load MUCH faster and run much smoother. This was with a V5 5500 at the time to. I'd sell you current Board and ram and buy a DDR board and memory. I'm pretty happy with my Shuttle AK35GTR. I'd just keep your current CPU for now as well.
