I just bought an A64 4800 X2 to replace my A64 3200. Currently my video card is a X1800XT 512mb and I have 2gb, (4x512) all matched sticks of Corsair PC2700 ram. I'm hoping that will keep me for a while but I have a question about my ram. At PC2700 and being 4x512 sticks, should I upgrade my ram? Will it make much of a difference? The ram is currently running on an Asrock 939 Dual Sata2 in dual channel mode. The timing of the ram is 2.5-3-3-7 2T. I do game on my machine but will a ram upgrade give me much more speed? So it's a cost vs speed thing, worth it?
