well lol. It seems that while I was at school, my dad already installed a 600W power supply on my system, with 35A total with a privatre 20A cable for the GTS.
Alas, there is no change in game performance. In CSS, for example, I get about 30-40 fps often times. Any other ideas about what is causing this, or are my expectations simply too big for the card?
Anyway, thanks a lot for the help.
