I would love to try that but I am running on linux (ubuntu) and so can't easily overclock as far as I know.
Unless people know otherwise?
2 x 750 (non ti) give me 4.1-4.2 on X11. Overclocked (see my other post).
planning to replace my 40 280x with 66 Ti's , will save 1/2 of power costs.
With the lastest driver, it's possible

I have share the info in this thread :
