iv decided that my computer could use an upgrade. the specs are...
ASUS P5K premium/wi-fi ap motherboard
Q6600 overclocked to 3GHz
9800GTX (factory overclocked)
4GB Corsair XMS2 800MHz 4-4-4-12
2x 500GB samsung F1 HDD
520W modular corsair power supply
im either goin to double the RAM or put a new GPU in, maybe a GTX280.
which would give the biggest improvemet in terms of gaming? also do you think the power supply could handle a GTX280?
thanks
