According to http://www.tomshardware.com/2006/05/23/amd_reinvents_itself/, only the top of the line athlon FX 64s benefit from the full affect of DDR2. I am planning to build a new PC soon with X2 3800 or 4000 (prices not too different for mobo and cpus for both am2 and 939), and I just looked at the price for DDR and DDR2 memories, for the price of 1GB of DDR2 800 memory with timing at around 4-4-4-8, I can get 2GB of DDR400 memory with timing of 2-2-2-5. According to tom's hardware tests, the same amount of memory for either case yields very similar performances with DDR even slightly faster. So of course having 2GB of DDR400 will give me a big edge in performance over 1GB of DDR2 800 for X2 cpu's.
So will it be worth it to go with AM2? will there be dramatic performance increase for DDR2's in the near future (before the end of the life time of a computer that I build now)?
