660 x2 or 760?

[Disillumination]

I already own a 660 and I'm thinking of getting another

 

Should I start a sli setup with my 660(200$) or just grab a 760(250$)?

 

i'm also thinking of just getting a 770(400$) but by the time i get the money for it, something newer would probably out

...and the 290(400$) seems like a far better value

For sheer performance - 660 x2

For Value - 760

And yes the 290 is a better value.

760 isn't much better than 660 definitely another 660

290 is the best choice though

290 is a beast

290@$400 is the best choice.

660 sli is pretty good performance.
if I had a 660 already I would get a 2nd one. because 760 is not much better than 660.

 

 

Edit: unless of course you are thinking about selling your current 660 so that you can get a 760 or a 770 then yes. that is also another good choice.
