SLI connection, is this right????

[Blt1684]

I have 2 evga gtx 660ti's, and I have them connected via an SLI connector. Here is my issue; when I'm in evga precision x I notice that 1 of my gpu's is running almost twice as high as the other. I can't remember but, at first I seem to remember them running almost the same. Is this right? Surely not because I feel like I'm not getting any boost in performance. I play gw2 and it usually runs at around 55-60 fps but, it was doing that when I only had the one installed. So what's up with that, did I just waste another $300+ on a 2nd card that isn't doing me any good?

is sli enabled in the nvidia control panel? Not all games scale well with more gpu's either as they are more cpu bound.

It may be caused by one Gpu running hotter than the other. Also know that the 660ti is limited by memory bandwidth making it a worse candidate for SLi.

Be sure to double check the SLI enable. I found there are TWO places you need to enable SLI with the driver I had.
