Sorry for the double post but here's what happened: the memory arrived today, and I think Vista does run better. I think my games run better too, and I was even able to start up Episode 2 and TF2 without Ep2 crashing and TF2 crashing as soon as I shot something. However, Ep2 crashed right after I spawned in the very beginning, right after that big video that recaps on what happened in Ep1, and TF2 ran pretty good (a solid 15FPS, I think?) and crashed as soon as someone on the other team shot a nade at me. Rawr. Well, at least all my other games work great. I was playing Zombie Survival on Gmod and it was pretty fun.
