Hi, I have an AMD Athlon 64 3400+ (939) in my rig right now and I noticed the other day that 939 dual cores are selling for pretty cheap. I really want to make a cheap upgrade to my comp, just so that it'll last me until quad core prices go down (wayyy down...I remember the x2 3800+ being $350). I was thinking of a cheap x2 3600 (mainly cuz its cheap and I want the new games that I play, like COD4, gears of war, ut3, etc...to take advantage of the dual cores) or maybe even an opteron (those get more expensive though..). Any advice or should I just wait it out till the prices drop on the quads...
