With AM2 comming out, all the leading platforms are going to be DDR2 so my question is this: should I buy DDR memory now or wait until DDR2 is available for both platforms? I already have an MSI mATX mobo and an A64 4000. I'm still looking for a graphics card too and I know I should wait on the graphics card as long as possible because those prices tend to drop but I'm curious about the memory.
