Folks, I know that this post is probably asking for the trolls to pop up,
but I figure I'll post it anyways. I am running on a Phenom II X4 955. I
want to upgrade, but I am waiting for the FX 8170 to appear...

Firstly, do you have an AM3+ mobo? Secondly, I've had both the x4 & now
the x6, both oc'd to 4ghz, and am sure the gaming bottleneck in my system is
not the cpu, but the videocard (a gtx 470). So, my advice is, get one of
the large but cheaper cpu heatsinks, overclock as much as possible, consider
upgrading the videocard instead of the cpu (I'd suggest a Radeon 7950/GTX
570/GTX 670(not released yet)), consider a SSD purchase, and wait for the
nextgen AMD cpus to arrive, not Bulldozer refreshes.
