1 x PCI Express x16 slot, running at x16 (PCIEX16) (The PCIEX16 slot conforms to PCI Express 3.0 standard.) * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. * The PCI Express x16 slot supports up to PCI Express 2.0 standard when an Intel 32nm (Sandy Bridge) CPU is installed. 1 x PCI Express x16 slot, running at x4 (PCIEX4) * The PCIEX4 slot shares bandwidth with the PCIEX1_2/3 slots. The PCIEX1_2/3 slots will become unavailable when a PCIe x4 expansion card is installed. 3 x PCI Express x1 slots (PCIEX4 and PCIEX1 slots conform to PCI Express 2.0 standard.) 2 x PCI slots

Im also running a Intel i5 3450 - 8Gb Corsair Vengeance RAM
Thank you for any help you can give me
More aboutcard mobo compatability confused
you have a really similar setup to me. I have the same mobo and can confirm that 6870's work fine. PCI-E 2.1/3 are compatible so dont worry!
The only PCIe incompatibility that I'm aware of is PCIe 1.0a motherboards with PCIe 2.1 graphics cards.
PCIe 2.1 and PCIe 3.0 devices work together. PCIe 2.1 was made specifically to work with PCIe 3.0 optimally IIRC.
