" rel="nofollow - Hi, I want to buy new graphics card, but Im not sure how powerful this card can be -
I have:
990FX extreme 6
GTX 780 in first slot (as primary, two monitors plugged in)
GTX 1070 in second slot (work 24/24, 7/7, I use it for render on background)

There are 3rd PCIe slot an I want to buy some graphics card to plug. So my question is:
Is it full-valued slot? Or some limitation here?
Whats the best nvidia card I can plug to this slot?

PS1: I dont need SLI, I need 3rd, independent card for render on background
PS2: PSU is not a problem, 1350W should be enough for all included FX-9590
PS3: everything should work on 100% (render) while I sleep

Thanks for answers, Shubol:-)

The website and page 16 of the manual states PCIE5, the bottom slot, operates at x4.

PCIE2 @ x16
PCIE3 @ x16
PCIE5 @ x4
