What I am currently looking at doing is upgrading my graphics card to a Powercolor 7950. From what I have read its size allows you to be able to crossfire later down the track if I need to.
Is there anything in my system which will bottleneck the results I can get from the 7950.
If so can you please list what I should also be looking at upgrading in my system to be able to create a good gaming rig that will be able to handle games well into the future.
Essentially your current PSU is really a 430W PSU, because the 12V rail total output is the one that matters the most. The TX 650 however, has 54 Amps on the 12V rail, meaing it can out put a maximum of (54x12= 648 W out of its 650W total).
