Older motherboard compatibility with Graphics Cards
I have an older motherboard and RAM, both of my GTX-280's died at the same time and I'm having an issue finding a compatibility list with my older components. The RAM and board still function fine my issue is figuring out a newer video card. These are my specs as I remember them.
With that board ANY modern graphics card will work fine as they are mostly PCIe 3.0. You board has PCIe 2.0 but 3.0 is perfectly backwards compatible and you won't notice any real difference. Therefore, just get any video card you want.
The board would support any new GPU as PCIe is backwards compatible and there's no gain of 3.0 over 2.0 whatsoever. The best you should go for, looking at the CPU, however, would be GTX 750 Ti, or else the CPU would bottleneck.
