If the socket is correct, you have the proper wattage requirements and you have some form of graphics, whether it's dedicated or not, then it should work.
If your talking about upgrading the CPU that's in the rig in your sig then I don't think that you will find much performance increase, however.
Just curious that's all.
My X51 R1 system is sadly maxed out. I'm eyeing going to the Aurora as my next system upgrade. The top of the line X51 R2, maxed out, and the bottom of the line Aurora, are very close in price. The Aurora has a lot of room to expand.
