I'm trying to finish my build and I'm too impatient to wait on Ivy Bridge for a slight improvement. My price range is 400 but I might stretch for Sandy Bridge E if its worth it, but will that last me at least four years before its out dated? Or should I go with more cores and the FX8150? I've only got basic knowledge on all of this stuff so I'd like someone else's opinion. Will hyper threading future proof me or will more cores future proof me? Thanks guys.
