So I've ordered a new GPU, an ATi Radeon x1950Pro. Quite a leap from my old 9800Pro and the x1300Pro I'm using now. It should arrive tomorrow or monday, and after that I only need to buy some more RAM and my rig is all set.
I would've liked to buy everything at once, but I don't have enough money to do so. Oh well, almost there now!
