5.6 Out of 10

In real terms, quad-threaded applications are thin on the ground and will be until at least this winter.

If a loving parent/festive myth figure/lottery win gave you a couple of hundred sterling more for your PC-building fund than expected then, well, it's a reasonable price for decent future-proofing.

Reviews Word on the street for the Intel Core2 Quad Q6600

But in terms of a re-encode/compress test and Stalker at 800 x 600, and it's quite apparent what two extra cores can do.

Unfortunately because it is old and there have been many new releases, 1366 1156, 1155 and now 2011, it is quite hard to recommend it, however if you do own one already I would always say don't get rid of it, keep it as a backup rig, this was truly one of those chips that could take a lot.

What People Are Saying Give it to me straight


You could usually hit between 3.2-3.6ghz depending on your motherboard, those P45 motherboards with this chip was a match made in heaven, obviously it required a SLACR (go) batch Q6600 and a low VID, but if you get lucky you could even hit 4ghz.

I did eventually keep it at 3.8ghz with 1.6ish voltage for over 4 years without any problems, this is certainly a touch cookie and one that will never be forgotten.
by munaim1 (Dec, 2011)
The max I could hit with my Asus P5E motherboard (flashed to Rampage Formula BIOS) was around 3.9ghz, however I couldn't stabilize it, the VID on my chip was a little higher than most (can't remember) and the motherboard FSB restriction didn't exactly help.

Socket Type

When I built it 4 years ago it was running like a dream, the temps were pretty decent and performance was great.
by munaim1 (Dec, 2011)


Honestly, I am upgrading soon to a SB system most likely, because performance in some stuff is iffy...but I'll be sad to see this guy go.
