I'm upgrading my MoBo to Gigabyte GA-Z77X-UD3H (Z77)
and my cpu to I7 3770K.
I have a Gainward GTX580 1.5GB (GTX580)
and a WinFast PX 8600GT (8600GT)
I want to be able to run 3 monitors,
while I don't really need a boost in performance.

Can I do that? Do I need the 8600GT or I can use the iGPU somehow?
How do I do that?

Thanks in advance!

what about the performance, of using non-SLI 2 GPU's?
I need the performance of the GTX580, don't care about the 8600GT, just 3 monitors with GTX580
