I was using a 3000+ A64 but it was my friends so out of his niceness he let me use his old 478 motherboard / Celeron 2.20 Northwood. I plan to get Counter-Strike Source, but I don't want to play it with mediocre graphics and only run it @ 20-30 frames. My graphics card is a XFX 6600GT 8X 128MB 128BIT. I'm also running Windows XP Home SP1 and 1024MB DDR333 Samsung. I really, really want this game, but I want to play it on high with atleast 40 constant frames.
