I'll see if I can increase my budget <_< because I need to get a new GPU, a new power supply (for the GPU :P), and two side fans...
On a random note: this would be a monster :P : Link

nVidia 460 is fairly moderately priced and shouldn't burn a hole in ur pocket and i think ur current psu can handle it...just barely although 550w or 650w psu should do it nicely. i'd recommend an Asus ENGTS card because Asus re-designed some of their cards to run quieter and cooler. just a thought.
