No. The E6750 will perform better in applications threaded for only single or dual core (99% of applications). The Q6600 will only perform better in applications that are capable of utilizing all 4 cores (very few applications today).
-.- if u could get a program that evenly spreads out the Processing between the 4 cores then maybe but i think there is none
4Core CPU will run better in a 4 Core supporting program (thats wat i meant)
But AMD has a download thing that does that for its 2 Core CPUs
he should get the q6600 no question asked. even though most programs are made for only 1 or 2 cores. he will be able to multitask like no other. also more and more games will become quad core capable
Eh, depends. Right now, you'd be better off with the E6750. Barely any current games truly utilize dual core yet, let alone quad core. If you want to try to future proof your system, go for the quad core.
go with the e6750 because theres no current software that fully supports quad core
up in a post above someone mentioned that games are just now starting to utilize dual cores which is true because i have a c2d 6420 and i play rainbow six vegas and it eats up one full core and has trouble utilizing both cores. it even states on the box that the game is intended for pentium 4s because it doesnt fully support c2ds...so theres just a little tidbit for ya!
now, im not an intel or amd fanboy, they both have pros and cons....however one thought about intels quads..they are just like two c2ds squashed together....my opinion would be to wait for amds full/true quad to come out..i think its call the phenom...i have no clue when its being released though...maybe someone on here knows......
