Well I would suggest the AMD Athlon 64 X2 4200+.
Much better than the 4000+. You'll be happy when
new games come out that support dual core and you
won't have to upgrade your cpu and motherboard.
If you get the 4000+, It will be hard to find a dual core cpu for socket 939, because AMD is launching
socket AM2 June 6, 2006 and that will be much better than the socket 939's. So I would suggest the Dual Core if your building soon.
If possible, I would wait for AM2. I'm
waiting for It to build my new rig.
Well. good luck
im gonna build a rig for gaming and i need help chosing the amd x2 4200+ or the amd single core 4000+?please need help
