I have a Athlon 3000+ and I was looking to purchase a OEM 3800 x 2 or 4200 X 2 939 from New Egg or Tiger Direct. Has anyone used their single core 939 Heatsink on a dual core 939 processor? I am just using the system as a HTPC for watching TV and burning DVD's, so I am not looking to do any overclocking. I just wanted to get another year to year and a half out of my system and then move to a quad core. Any information would help. Temp is my main concern ![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
