How do I know if this will work with my PC I have an old PC but it does have an i7 processor and currently and ATI 4800 graphics card. I need to upgrade the card and need to know if this card will work with my PC. The current interface is PCI express 2.0, will this card which is PCI Express 3.0 work ok?

Yes pci express 3 cards are backwards compatible to pci exp 2.

Yes, it will work. PCI express 3.0 is backwards compatible with 2.0. You may see very slightly lower performance with a 2.0 slot instead of 3.0 but you probably won't be able to tell the difference.

As far as i know the pci express slots are backwards compatible. So you can put a 3.0 card into a 2.0 slot, but not the other way around. That being said it just may not get the optimal speeds because of that
