A snippet from gigabyte.
1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
Those slots run at different speeds...they share bandwidth and other weenie stuff.
If I move my GTX 560 ti PCIe 2.0x16 graphics card to slot 2 will it decrease the performance.
