Currently looking for a new Graphics card and managed to narrow it down to the two in the thread title. The problem is, I don't know which is more suitable, despite the fact they're both roughly the same price as of late.
I'm worried about whether or not my Truepower New 750w PSU would be enough to power the 7990, seeing that it's a power hungry beast.
Also, I have a HAF 922 Case -- is this large enough to accommodate the 7990?
My native resolution is 1440p and I usually play Arma II on the machine.
Id take two 7970s before id take a dual GPU single card....but with Xfire issues still only partly solved, wouldn't go that way....given yur choices, Id stake the 780 but I do way more dual 770 builds than 780s
