3-Way Crossfire or SLI

post #1 of 5
Thread Starter 
Ok, Been searching online for a while now and i have to ask;
Why some cards have 3 way SLI/Crossfire (2 ports) and others have only 1 (max 2 cards) in the same model ?
I noticed that with the Geforce gtx 660 and radeon 7870
Now I know most don't have a psu big enough to support this, but that cant be the reason of doing so! then why some have it and some not!

GTX 660's only come with 1 as they can only do SLI, GTX 660 TI's come with 2 as they can do 3 way SLI

Nvidia probably figures that the people who buy the most expensive cards are the most likely to use multiplecards, as the number of high end GPUs sold is extremelysmall, and multiple card users are only a small subset of an already small group. This saves them money, while also up selling the higher end models.
