AMD Athlon 64 x 2 6000+ 4 ddr2 gigs ram, adding 4 gigs of ddr2 ram, and replacing the nvidia GF8200A (V1.0) Motherboard's 9800gt 512 with a hd7770 1 gig gpu a viable way to go about this? I've been looking through site after site of the best possible combination. I have 650W PSU. Would this be possible? Does adding 4 more gigs of ddr2 ram when the gpu will take most of the brunt help? Will the ram help the cpu from bottlenecking? And most importantly will this ruin the mother board... please help bring this into perspective for me..
