I will Probably swap the GPU in the future, but compared to what I have now, It will do fine for games I play (If not better).
I can run most Source games smoothly with a 256MB dedicated Ram Graphics card on Medium, a 1GB would be perfect for me.
8GB of Random Access Memory and a 6 Core Processor should be pretty efficient for my very humble demanding games. Seriously, the only game I own that requires some decent Specs is TF2.
