Nice, been thinking of changing my video card, been having nothing but trouble in Linux and pretty sure it's the video card. I have a GTX 560. Might even go ATI. I have some debts to pay before I put more money into this machine though.
Since I don't game a lot I'm even debating on going with something lower end, I hate the fact that my PC uses more power than all of my servers combined. I'd like to put it on the big UPS but I'd hate for it to add such a huge load on the run time. On the other hand I do game sometimes so I'd have to be limited by the video card.
