Update ! so I have been using this rig as my daily beater. Mostly because it's the quietest rig I have (600 RPM fans on the CPU rad for example and only two) and secondly because I just love this rig so much. It's built like a brick out house, has features that just rock (like a button on the back that lights up the entire back outside so you can see what you are doing).
Well the other day I thought I would take a look around to see what I could find in the CPU department. I firstly considered getting a 3930k or something but I was certain that it would be wasted in this board (X79 UD3) as it has pants phases and you can only get about 3.6 ghz or so before it craps its pants.
I was certain also that I had the Rev 1.0 board which is even worse than the 1.1.
Any way after a lot of research (and nearly making a terrible mistake !*) I found one of these on Ebay (note I drew this using the actual CPU to take everything from)
OK so this is where it all gets a bit weird. It's called a QE5F. If you look around using that as a search word it brings you to a Xeon E5 2680 V2. However, the E5 2680 V2 is actually a ten core CPU, not 8 core. But this thing is called the exact same name and even has the 25mb of cache that comes on the 10 core model, but still only has 8 cores
Very strange. Any way, on Sunday (two days after I had ordered the CPU) I found out that it does not work on Rev 1.0 boards. On Gigabyte's site it says 2680 but if you look over to the right it says N/A. In other words it does not work. Why Gigabyte did this instead of just not listing the CPU god only knows.
So I was kinda worried that it would not work. I decided to get out my torch (flashlight) and have a poke around and I noticed it said Rev 1.1. I quickly went back to Gigabyte's support list and....
PHEW. So this made me happy. The CPU came today and I fitted it and... Well it works
So I ran some benchmarks.
Before - 2ghz boost on all 8 cores, Ivy EP.
Cinebench.
After, 3.1 ghz boost on all 8 cores. Ivy EP 25mb cache.
It's about 100 points short of a stock 5960x. Well, one that boosts to 3.3ghz. For £100 it's incredible..
Couple more benchmarks.
3DMFS regular (not Extreme)
3DM12 Time Spy
So this rig has now become my daily rig. Just need 8gb more RAM when I am not so skint and it's not so blood suckingly expensive and I will be all set
*I thought I had a V1 board and did not read the chart correctly. Doh.
