Sorry that I was gone for so long, but here is the final update: It turned out to be the RAM. I got a new stick today and my system runs better than it ever has with it's 4GB.
Thanks for the advice guys! For so long I was convinced it was my 4870 at fault, but it wasn't. Kudos to Visiontek for replacing a perfectly good 4870, I will definitely by buying my next graphics card from them.
Also, GSkill deserves props for a swiftly dealt with RMA.
