Coolermaster isn't generally know for top quality power supplies, but you can pretty much run any single GPU card setup you want with the 2600k or 4770k.

1. Your top upgrade with that motherboard will be a 3770K. Really, not a big enough jump to be worth much.
A 4770K will need a Z87 motherboard and socket 1150.

2. If your psu is TOP quality, you might be able to run a GTX770. More likely, a GTX760 or R9-270X

Coolermaster, psu is not that good, I would not upgrade anything with it.

Thank you for your help. I am using 3Ds max for designs and unfortunately i cannot afford a workstation for now...that's why am more focused on the CPU power more than graphic card capacity.
