It should work. All of the cards should have DX9 capabilities. Are you upgrading your whole system or just the video card?
Make sure to get a new power supply as well.
I figured that I just didn't know if I would be taking a big performance hit with DX9. I'm upgrading just the video card for now it's the last thing to upgrade other than the OS. I have a Seasonic 500 Watt modular PSU that should be more than enough.
No worries, mate, the latest and greatest will still run DX9, although they'll often take a bit of a performance hit ( my Win 7/HD6950 will run the original Unreal, and that's a DX5 title!).
More detailed specs would be helpful, though-some older PCI-E 1.0/1.0a motherboards have issues with PCI-E 2.1 cards.
BUT, dependng on what one is currently installed, you may need to replace the powersupply to cope with the replacement card.
Ok good. How much of a performance hit do you think you will take in percents. This is a recent Z68 motherboard so it has the latest 2.0 or 2.1 PCI-E slot.
Case- Couger Solution
Motherboard- FoxConn Z68A-S
PSU- Seasonic 500 Watt Modular PSU
Videocard- Probably a GTX 650Ti or 660Ti I haven't decided yet
