Using 2 Seperate GPUs to bypass 4 Monitor Limit?

Alright, so this will seem like a really weird question, but, I've got a gtx 1070, and I've already got 4 monitors hooked up to that, but I also wanna be able to have my TV hooked up to my computer so that I can watch stuff on a bigger screen (mostly tv shows and anime, ect), as well as being able to use my HTC Vive without having to unplug one of my current monitors (I'd switch one of the ones I don't use for anything graphic intensive to the other gpu).

The main question is, is there any key drawback to me having both my current gtx 1070, and my old 660ti both in at the same time, just to allow me to have more than 4 active displays?

In the BIOS there is often a setting to enable it also with a PCIe card, or else you could just make the IGP the primary video adapter.

GTX1070 is rated 150w TDP and the GTX660Ti is also 150w. Should be fine so long as it has two 6-pin and an 8-pin, or four 6-pin (whatever your cards take).

As said, the primary drawback is using more power. But then connecting 4 monitors to the 1070 will already not allow that to drop to idle clocks ever.

So long as you are not running Vista or Windows 7, you can run multiple adapters that take different drivers. If your motherboard has the right output (such as HDMI) and its CPU has an IGP, then often you can enable that instead of using a 2nd GPU.

My PSU's current wattage is only 750.



Yeah, I hadn't even considered my IGP, but doesn't having a GPU usually disable it? (Kinda new territory for me) How would I re-enable it if it is disabled?
