Alright, it's been awhile since I've worked on my desktop and I really don't know much about parts anymore. The purpose of the computer is for gaming. Just so the first posts in this thread aren't all "Why the fuck did you get a 980X for gaming," I have relatives who work for Intel and I got it cheaps.
Here are my current specs:
CPU: i7 980X OC to 4.0ghz
Memory: 3x2GB @ 1600mhz
Mobo: GIGABYTE GA-X58-USB3 LGA 1366
Graphics: Crossfired 5850s OC to 1000/1200
Case: COOLER MASTER HAF 932
Power Supply: I think it's a 1000W Cooler Master Silent Pro
Operating System: Windows 7
Anyway, I know my graphics cards have to go in the upgrade, but should my cpu/mobo also go for Sandry Bridge? My budget will hover around $1000.
