Don't mean to hj your thread, but when I saw 939, mmm..memories. I had a 939 Mach Speed MB with an athlon 3800+, 2gb ddr and a nvidia 7300gt. I put my 7300gt through so much shit, im surprised it lasted the 2 years I had it(06-08).They just don't build hardware like they used to. I loved that machine so much, may it RIP.
OOh, come to think of it, I still got my 7300gt up in my closet collecting dust. Should pull it down to clean it, and look back at the good old days we had.
OP, theres no quad core available for the 939 socket, only daul cores.
