Should i get 2x GTX 560s non ti or a GTX 670? Heat and power consumption are not a problem. I found a pretty good deal with the GTX 560s and i want to know if i get more performance then a single GTX 670? Thank you.
No, in every case I (as well as others) will recommend a single powerful GPU versus 2 less powerful GPUs, even if they are faster in SLI /Crossfire. This is due to SLI/Crossfire instabilities in games when the drivers aren't properly coded for that purpose. Also, (not affecting you) there is more heat and a higher amount of power consumption.
Two GTX 650Ti's are able to out-perform a GTX 580, but a GTX 670 can do that on its own. Since you are talking about to GTX 560s, then a GTX 670 will definitely out-perform the 2 cards in SLI.
Personally I would get a gtx670. If you mean $330 for one gtx560 then I would definitely not go with that. A gtx670 is $~370 depending on where you live. Two gtx560s may offer the same a bit better performance in a game or two, but you could encounter driver issues, scaling issues, micro-stuttering, and a bunch of other potential problems. So overall you could very well get lower performance with to gtx560's. A gtx670 is a very good card and it should handle any game you throw at it at more or less Max settings. Also in the future you could just add another gtx670.
I don't live in america or anywhere near.
I live in albania and prices are like 10 times bigger so a gtx 670 here is 810 usd (600EUROS)
Honestly, you are still going to get a better deal with the GTX 670 in terms of performance. Plus, you won't have to worry about driver issues causing micro-studdering, or low FPS in games (I'm assuming you want this to play games and not any other form of professional use). And I'm not sure how much this will affect the price, but can you order from a US store, then pay the shipping and duties?
