This is a beast of a Cpu! I put mine into an Asus server board but this might fit into an x79 board (something I had trouble getting clarified from online forums for some time). I use mine for everything between content creation to recreation, and then some on the side. It's a solid performer.

If Sandy Bridge E showed us anything, it's that the current crop of mid-range desktop CPUs, such as the Core i5-2500K are actually pretty good, especially when they're overclocked and dealing with tasks that aren't too heavily multi-threaded.
