Well i am looking at getting a 4600 x2 here very shortly, i have an asrock dualsata2 board so i can get the AM2 cpu card for it and go with a AM2, but am i required to use DDR2 with AM2? or can i use my current DDR, since i have 2gb of DDR at the moment i don't really want to get rid of it and get DDR2 just yet, cant afford to do that at this time. Otherwise ille just have to get a S939 4600 x2.
