Motherboard is a X79-UP4 Monitor is Dell UP2414Q 4k panel 3930k cpu PCEi slot layout; http://www.techpowerup.org/uploaded.php?file=140217/mobo.jpg From manual Expansion slot info; 2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2) * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. 2 x PCI Express x16 slots, running at x8 (PCIEX8_1, PCIEX8_2) * The PCIEX8_2 slot shares bandwidth with the PCIEX16_2 slot. When the PCIEX8_2 slot is populated, the PCIEX16_2 slot will operate at up to x8 mode. (All PCI Express x16 slots conform to PCI Express 3.0 standard.) 2 x PCI Express x1 slots (All PCI Express x1 slots conform to PCI Express 2.0 standard.) 1 x PCI slot Card's I want to plug in; 2 Geforce Titans 1 LSi 9266 4i 8x 1 Soundblaster PCIe sound card 1x Layout would be, Titan LSI card Titan Sound Card In each of the 16x slots. I am strongly considering selling my 3930k for something in the Ivy bridge category to get PCIe 3.0 . Normally, I wouldn't bother, but with lane speed becoming an issue related to the processor. It makes sense somewhat to me. Thoughts?
