By the sounds of it you may be in the same position as me. I always keep my PC up to date with the latest components for gaming, and because I use it every day for my work day in day out (Computer Science PhD Student). I love my PC. I my 920 D0 stepping CPU in I believe around 2008/2009/ Since then it's had 3 new graphics cards, a new SSD, two new hard drives, a new motherboard, a new case, yet again another new case, new memory, a new CPU cooler, but the CPU has remained the same. I keep coming back to OcUK thinking surely it's about time that can be upgraded. Every time,... no,.. it's not really worth it! These CPUs seem to have lasted a life time and seem like they were fantastic value for money.
Yep, still on an i7 920 clocked at 3.8Ghz. I keep thinking surely it's time to upgrade - pretty much all the rest of my kit I got at the same time has been. Probably the best value chip I've had!
