Thanks guys :) I can afford any one of them, just need to know which one is better and more reliable, and please don't just say " the most expensive one" thanks :)
 
fairly sure the 6790 is, but i'm not sure since the 6770 vapor-x has higher clocks, i don't know how much the 128 v 256-bit memory affects it.

but you said you ordered a i7 system, anything you order unless you ordered a special psu will need a much better power supply, which is a good chunk extra.

My power supply is 500w will that be enough?
 
a 500w power supply would be bare minimum for that card. But you still have to find out if your 12v rails will be enough for the card as well. I would say just get a new PSU if you want to get a new graphics card.
 
well a quality 500w would be fine for a 6790 as long as it is a good one, but what is the exact model of power supply you have? If you tried putting a 6790 with a crappy low end psu that claims 500w, then you're going to have to replace most of that computer most likely.
