Okay so my specs are asus m5a97 mb, fx 6300 cpu, gtx 570hd gpu, 2x4gb ripjaw ram, 500gb hdd, two 120mm fans one in front and one in the back, corsair 750w modular, and a hp disk drive. please help me out with some suggestions.
upgrade that gpu to something like a 960/380 and change out that psu to a quality EVGA, XFX, Or Seasonic unit. Most corsair units have cheap capacitors in them and die before most other psu's. I recommend an EVGA g2 or gs series unit.
Upgrade GPU is the simple upgrade, PSU is fine since it will not be stressed with a single GPU. You did not specify budget but SSD for OS and programs will make it snappier.
