which cpu should i use? i own two computers. one is sporting a core2duo e6750 and the second has a core2quad q6600. i do a bit of multitasking but only while surfing the web. i play a few games. crysis. pro street. tiberium wars. world at war. civ 4. aoe 3. i have my quad overclocked to 3GHz 1333fsb. but have gotten it to 3.4GHz i have never overclocked my duo. i guess what i am asking is... which would be better for gaming? an overclocked q6600 at 3.4GHz or a e6750 with unknown overclockability.
