I am currently upgrading my computer and looking at different video cards to put in and was wondering if my mobo would be able to support the GTX 660Ti. I could have sworn I read on here somewhere that some mobos are able to get an update to their BIOS to be able to support PCI Express 3.0 and was wondering if mine was one of them.
It'll be fine. PCIe 3.0 cards work perfectly well in 2.0 slots. And no, there's no way to make your 2.0 slots into 3.0 slots. That's only possible with an Intel Ivy Bridge CPU on a 6 or 7 series Intel chipset.
