i have 2 gtx 660s both are pretty much brand new 1 is brand new and i think i have a bad slot is my mb atm its what i was told from a computer tech
You dont have a bad slot. You simply lack a second x16 PCI slot. The other big PCI slot might look like a x16 but it is electricaly wired as a x4 slot. Since Nvidea requires its cards to be connected to at least a x8 slot to run in SLI your mainboard cant run SLI.
But i agree with Penguins0690. Sell both 660 and get a 390/970.
