Even better, it boasts almost as much overclocking headroom as the more expensive QX6950 model.

If anyone who still likes socket 775 this is defiantly an upgrade you should consider.

This is one of my all time favorite processors it tough overclocks well, it was expensive, but has remained stable as anything for years and ran everything i threw at it.

Overall

9.4 Out of 10

What People Are Saying Give it to me straight

Socket Type

This processor is great for those who are still stuck on 775.
by Socom (Nov, 2011)
But if you can stretch to the anticipated £250 price tag, you won't be disappointed.
by Tech Radar (Feb, 2008)
My current one has been running like a dream for 2 years, and I don't expect to give it up any time soon!
by Polska (Nov, 2011)

Price

The processor is still fairly expensive given that its an older generation.
by Polska (Nov, 2011)
Cons: Can be expensive depending on where it was purchased.
by Socom (Nov, 2011)
It will be cheaper if you are still on an LGA775 board though so definitely something to consider if you are not ready for a full rig overhaul!
by Polska (Nov, 2011)

Socket

It had no problem getting to 3.5 GHz but my motherboard was restricting anything past that.
by Socom (Nov, 2011)

Cooling

CPU fan/heatsink was a akasa freedom tower.
