Do I need an Upgrade?
CPU: Intel Core2 Quad Q9400 @ 2.66GHz
GPU: HD 4870
PSU: 500 watt
MotherBoard: ASUS P5QD Turbo
Should I upgrade the whole system (new CPU, RAM, MotherBoard and GPU) or just the GPU?
And for the GPU should I go for the GTX 660 /660 ti or wait for the new HD 8000 sieries from ATI?
