UPDATE 1:
The motherboard which I am planning on getting is the Asrock P67 PRO3 SE. Is it possible to get a motherboard which can do true x16 in both ports?
ORIGINAL QUESTION:
I am about to buy 2 gt 430 graphics cards so I can connect 4 monitors. According to the spec of the card, it has a pcie2 x16 interface. I have chosen a motherboard which has 2 pcie2 x16 ports, but has (x16, x4) written next to it. Am I right to assume that mean that only 1 port is true x16 and the other port is x4? If so, does that mean I can't plus in 2 x16 graphics cards?
This usually means, that it'll go 4x / 4x when you plug in both cards. Please, share the motherboard's manufacturer/model. (Btw. usually they run with 8x/8x Pci ex speed.) ALSO: The reason it says x16 on BOTH ports, is because both ports are x16 BY DEFAULT. When you plug in only ONE card. But it doesn't really matter. x8/x4 will be more than enough for such a card, and your PC will run without any problem.) – Apache – 2011-12-22T11:14:49.503
It's the Asrock P67 PRO3 SE. Please see the update in the original question above for a direct link to the spec of the motherboard. – oshirowanen – 2011-12-22T13:05:58.143
