I have an IP35 Pro XE motherboard which has two PCIE slots.
One is x16, the other is only x4.

I have a GTX 660 in the 16x slot.

The question is, if I put another card in the x4 slot will the card still operate at its maximum capability for searching or will it be limited because the slot is only x4?

My mobo does NOt do SLI.
