I think there are motherboards out there that have multiple x16 slots
that can be used non-SLI if that is what you want. Look at
motherboards and go to the manufacturer websites, download the manual,
and make sure it does what you want. If you only want two monitors, I
recommend just using one card with two ports on it. They almost all
have at least two ports now (even the above), so that should work just
fine. Do a little more research and be sure to dig deep here. Let us
know if you have more questions.
Just to confirm here - systems with 2 PCIe 16x slots are indeed available.
Intel has a fantastic one - D955XBK.
I know this isn't AMD, which it looks like you're after, but I really
need to mention this board as I've built systems with it and it's the
sweetest Intel board I've ever used.
Regards,
Ed.
Oh, and yes, the customer I sold it to has added a second 16x display
card, and yes, it is working apparently.
