Done. I'm not exactly sure on some of the questions but gave my best guess. I never really experience major framerate drops that I can tell, though occasional rubberbanding/lag happens =P
Video card I put Nvidia GTX 400 or newer. I'm using a GTX 770, and Nvidia is weird about their model numbers.
Processor is an Intel Core i7 860 @ 2.8 GHz. No idea how old it is, but I'm pretty sure it's still the original one I built this computer with, and I've had the tower for 10+ years. Only ever upgraded the GPU and ram, and replaced the hard drive after it fried.
