So... What's the different between GTX 660 SC and GTX 660 Ti?

I'm getting 3 of these. Currently I've decided to get 3 of GTX 660 SC. Decided to get Radeon HD 7870 Crossfire. I got the Asus p9x79, can they be on that mb?

GTX 660 uses the GK106 chip. it has 960 cuda cores with a core clock of 980 mhz and 1033 mhz boost clock. 192 bit memory with 24 ROPs.

GTX 660 SC is a factory overclocked GTX 660 card. 1111 Mhz boost.

GTX 660 Ti uses the GK104 chip with a SMX (192 cuda cores) and a 64 bit memory controller disabled . 1344 cuda cores at 915 mhz core clock and 980 mhz boost. 192 bit memory and 24 ROPs.

GTX 660 Ti is atleast 15 - 20% faster than GTX 660.

try and restrict the number of cards to 2. performance scaling beyond 2 cards starts to fall off. go with GTX 660 Ti SLI.

Plus, you can SLI 3-way with GTX 660 Ti but only 2-way with GTX 660.

Welp... Can't you 3-way GTX 660 SC.

GTX 660 SC is just basically GTX 660 overclocked so only 2-way SLI is possible.
