Everything I've seen to date indicates that the difference ------------for GAMERS----------between a 6-core and an 8-core CPU is hyped far beyond ANY rational reality. In the gaming world, the GPU is king---------------the CPU is the support structure, and like others have said, the Gaming world doesn't (yet) know how to truly use more than a 4-core CPU. (Yea-----quite a few qualifiers aren't there!!). My personal feeling is this:
Buy the equipment you need, and plan on "some" growth before maturity (about 2 years or so). I'm still running a quad-core CPU and able to run ANYTHING I want, easily. ------------------Yeah, the "latest and greatest" --------------MIGHT------------show some improvement-----------but then again, will I even notice?
At this point, I'm waiting for AMD to announce it's latest socket config (sometime in 2015). At that point, I MAY consider an upgrade---------------but probably not much better than a 2nd tier AM3+ MB and CPU.
