EVGA Superclocked 660 or Superclocked 650 Ti Boost?

[Craigrox]

Hello,

I am looking at buying a new GPU, the price difference of the two is only £20. HWCompare lists the 660 at being much faster, however I believe the information provided is not in accordance with the superclocked 'boost' model of the 650 Ti.

What are peoples opinions on these two cards?
EVGA GeForce GTX 650 Ti BOOST Superclocked
EVGA GeForce GTX 660 Superclocked

Here is the HWCompare page

I am using the EVGA 650 Ti w/o problems. Cinebench 3D gets 44 fps with this card. Have not tried using in Premiere pro or with any CUDA apps. Shows up with a weird name on System profile.
This card is not supposed to be great for gaming but it is small, runs cool and quiet and is supported OOB in OS X 10.8.3.

Does it have fan speed control by chance? Looking to get one, and was wondering if the fans run on full black the whole time, or if they change speeds. Thanks so much!
