660 TI for linux CUDA

Hello,

I am building a computer for cuda and some computational physics projects and I want to use 2x660 ti cards.

I am thinking to get http://www.evga.com/Products/Product.aspx?pn=03G-P4-3668-KR a evga with 3GB vram and asus with 2 GB vram http://www.asus.com/Graphics_Cards/GTX660_TIDC22GD5/ .

The evga is over-clocked, I am not sure about the asus cards. Did anyone use the evga for cuda. Are there any problems with overclocked cards, thoughts???
