Hey guys, I've got a Gigabyte GA-K8NS-939 mobo with an Athlon 64 3200+ CPU. I am running 1gig of GEIL RAM, PC3200 (CL2-3-3-6 Ultra-400) and the performance isn't what I was hoping for. I have some questions: 1) Should I stay at 1gig or go to 2gigs? I play a lot of new games and want performance! 2) Would it be better to go with a high performance RAM company like Corsair? I know the on-chip latency is a bit lower than what I have...but will I even notice? 3) Should I buy 2 matched/paired 512 sticks and run them in DDR, or go with 2gigs instead? 4) If I go with 2 gigs, can I use my existing GEIL sticks AND 2 new Corsair sticks...or do all 4 of the sticks have to be the same? 5) Can I use PC3500 instead of PC3200? Thanks for the help with these questions guys.
