bastarddk: A simple question deserves a simple answer.
Which can not be answered until TW3 goes live. See my previous responses...
"I think the 480 will run TW3, but I wouldn't expect much TBO."
"If you are on the fence about an upgrade, wait for TW3 release, try it out and if you are not satisfied, pick up a new graphics card. I'd stay with Nvidia too, TW3 is a GameWorks title."
" If the 480 delivers what the OP is looking for, then he should be happy. If not, only an upgrade will fix that"
bastarddk: Heat and power consumption has nothing to do about being able to play TW3 with a GTX 480. That's pure FPS. GTX 480 is on pair with the GTX 660 when it comes to FPS.
I wasn't implying that heat and power consumption have anything to do with raw performance. If you re-read my response you will understand that it was a general comparison of the 480 and 660 showing how the 660, overall, is the better gpu. It had nothing to do with TW3 or frame rates. Or upgrades for that matter.
I'm not here to argue with someone over semantics and opinions. I simply gave the OP my opinion that's where I leave it.
@taltsahi : I hope everything works out for you.
