I thought those lenovo's with the sli had a 2nd video card in lieu of a dvd drive?
Nevertheless they're awesome.
They share the same Bay. ... so you remove one to use the other, but mine came with both. ...I just choose which I want in the bay.
I don't really use disk any more so I just leave in the second vid card.... and yes it runs great, especially for the price.
The only trouble I have had is with throttling the vid cards in certain games. .. I have to enable vsync and limit the max frames to 60...otherwise they jump to 110-209 fps and it was causing alot unnecessary heat issues... but throttling to vsync gives a constant 60fps and with a cooler never gets hot. It was pumping out some serious heat though till I saw how many fps it was putting out.
