I have and Intel Core 2 Duo e6550 @ 2.33ghz, 3 GB dual channel DDR2@399 and a Nvidia 1536mb GeForce 8600 GT. I am running windows 7 32 bit home premium. I around $100 to do an component upgrade. What would be the best bang for my buck? What would the possibility of overclocking be? Any free suggestions would be great also. Looking for better performance in games and in video playback quality. Thanks.
