Either that or just buy a used 670 if you can find it for cheap.

I'm looking for just that, of course getting a 670 for 660 Ti price would be ideal.
been looking for some recent driver benches / charts for Surround resolutions but can't find any..
I see lots for 2560 x 1440..

and I'm not @ 5760 x 1080p, currently @ 3840 x 1024 and soon to be @ 4800 x 900..

I get exactly where you are coming from, and in that situation I also get exactly why you are concerned about the memory bus width. And don't get me wrong, I'd love to have some hard facts as to how much impact it has on performance.

Unfortunately, it seems like the only way to tell how a given card/s will perform on a given setup is to try both and see. And if you had that sort of cash to splash around I don't think the question would even be being asked. As it is, you're basically buying blind. So I understand your purchasing dilemma, I just don't think anyone can really break it down to the specificity of bus width.

I'm guessing the 660Ti is around $310 and the 670 around $390? FWIW I run most of my games at 3200x1350 (or above) which is the exact same pixel count as 4800x900 and I've not run into any drastic issues. Same 670 model as you. And I will be going SLI mainly just to crank all games up to 3840x1620 and kill jaggies for good.

Looking at benches between the 660 and 670 it looks like the 670 is 10-20% faster than the 660 depending on the game. Given that the only difference between the two is that the 670 has 33% more ROPs and a 33% wider bus it doesn't seem as though either of those differences is fully accountable for the 10-20% performance increase. Clearly it's not a perfectly linear scaling.

So while I'd assume you'd be fine with the 660Ti, if it were me I'd think hard about the 670 just for the peace of mind that I'm not being held back by the lower ROPs and narrower bus.

this exactly...
post #4265 of 8948
but at same time he isn't even at 1080p surround. either choice is fine. but you could find a used 660ti even cheaper.

someone let me 'borrow' SLi Titans..... I'll give them back I promise..
sooner or later.. biggrin.gif

Keep in mind amd has no fully fixed the screen tearing on the 79xx series. Unless you get one with all display ports (at least three like the DC2/T or Lightning).

Got rid of the 7970 I bought quickly because of this issue. Ppl are saying its hit or miss but I've seen quite a few Tahiti owners switch over to kepler for MMG.
