Yeah, I know the cost is awful. But I have an OEM Windows licence, not a box one, so I'd need to add a new one to the cost of a mobo/CPU/RAM replacement. :/
The mobo is Asus P5Q-E. The rest is an nVidia 460GTX (the Gigabyte version with a larger heatsink and two fans ex factory), an SB X-fi soundcard (which I'd bought to take some processing load off of the main CPU), and an old Samsung F1 HDD.
I'll buy a new PC when things get better at work and I can spare more cash, but so far I can usually achieve the 30 fps with nice settings in games, so I'm in no desperate hurry. I don't have much gaming time these days, anyway. So I'm basically only after a RAM upgrade at this time, but the cost is quite ridiculous. As in I can buy a generic 2x2GB set without a heatsink for about 50% of the cost of designer sticks (Geil, Patriot, OCZ etc.), but it kinda makes no sense to me to buy RAM without heatsinks at this point and lower the solid thermal properties I have right now (they can take some serious heat).
