It wil run with that psu, but a i7 920 is worth a better card than a 6770 imo. Depends on if you wanne game with it, if so i would buy a nice 500W psu from Antec, Corsair, XFX or Seasonic and put a HD6870, GTX560Ti or even a HD6950 in it. ( if your gonne upgrade in 1-2 years the 560Ti is the best choice i think.

Btw if you gonne built a high end system over 1-2 years maybe better get a 750W if you wanne sli or crossfire in the future.

Thanks for the good advice (again). Do you think my cooling is good enough to run one of those upper tier cards you mentioned?

I shouldn't talk because i use a test bench. But i would get like 1 or 2 120 mm fans. Depending on your case....

Depends, do you have a case fan blowing hot air out ( or cool air in ) ?

It blows out hot air. I need to go home and look if the darn thing even has another place for an additional fan.

I believe I have some sort of fan sucking in from the front-side vent as well. I will have to double check it. If I do have that, I think i'll go with your suggestion of the 560ti. Thanks again for helping a newbie.

Anytime.  

get a gts 450 or a gtx 550 ti and buy a 500w psu make sure it has all the connection you need and/or get a gtx 260 it is still a upgrade
