Yes i was thinking along the same lines i just had to check with a more experienced person. i am using ddr2 but i have 3 2GB sticks and a 750gb hdd that i was trying to salvage to save money. the GPU is complete dead weight trying to play my games, so it has to go. i was planning on forking out the money for a new motherboard and possibly GPU, but is the processor that much of dead weight as well? I have two other desktops which i was going to check their CPUs and motherboard to see if they are compatible with my RAM. Sorry to bother i am not well versed in hardware.
