i currently have one stick of 512mb pc2700 memory in my computer( i think 2700 is the fastest it iwll support) and i want to build a new computer in january or february. i figured i will start buying some of the peices little by little(not the ones that might drop in price, im just getting memory and a low end graphics card) and put them in this machine and then when i build mine put them there. i have room for 2 sticks of memory and owuld like to buy a 512mb stick of pc3200 memory so i can have a gig for now, and when i build the new one take it out, and go back to 512. is it gonna be a problem to have a pc2700 and a pc3200 stick in the same machine? my other question is this... for just plain DVD shrink.. which would be better an athlon 64 3000, or a P4 3.0? just dvdshrink, im not talking games or anything else.
