The MSI H81M-E35 has PCI-E 2.0 lanes, so it will not deliver performance like a motherboard with PCI-E 3.0 would. The graphics card still works, though.

You'll be fine, the card is backward compatible and still won't fully fill the PCI-E 2 bandwidth

Why wouldn't it fully fill bandwidth?

Last time I checked, a few months ago, no single GPU fully utilizes PCIe 2.0. SLI is a different story. But in terms of performance, a PCIe 2.0 will have little to no difference between PCIe 3.0.

The bandwidth available in the PCI-2 spec is more than todays cards can fill (one of the reasons that AMD seldom uses PCI-E 3 slots (to save money, the 3 cards run fine in 2)....PCI-E 3 is more efficient, but will notice little to no difference performance wise - sort of like DRAM (DDR4 is more or less a continuation of DDR3, originally DDR3 wasn't planned to go higher than 1600 - the people wanted faster, and the manufacturers obliged, creating faster - that's why all this new DDR4 has such high CLs)

Thanks for clearing this out to me. :)

Any time. This is a learning community which is why I usually just read threads and seldom post anymore. I don't have the time to always help out.
