I dont know. Maybe an E8400 would do the trick. IMO quads are over rated. Just get a nice dual. See when coming from amd to core 2 its like a whole other world. Something strange I couldnt believe they could pack such a punch into a Core 2 dual. They did just that ... YOu wont even need a quad Pioneer. The quad guys are the guys who usualy bench. IMO Just get a dual.
Also to Lemans .. Sorry man I havent been looking anywhere for prices but the egg.
Believe me. If you got an E8400 which would do like 4.2ghz the quad wouldnt be able to keep up with you.
