Thanks for the advice, however there are a few other things I forgot to mention.
I bought PC this 3 years ago when I was 14 and didn't know much.
I got the GTX260 for free from a friend.
It came with 6GB of DDR2
The biggest bottleneck atm is the CPU (65Watt and it doesn't have ANY L3 cache)
The GTX 260 is overclocked and running rock solid at 725MHz core, 1485Mhz Shader, and 1215Mhz Memory (2430Mhz effective)
This PC was only meant to be a stepping stone for me to learn and practice working with computer components.
I don't intend to do any more upgrades on it, (like you said it would be a total wast of money) This thread was mainly for people who were wondering if a larger video card or a more powerful CPU would work with the Motherboard.
I can't wait to do a new build
