Windows GFX card in 2008 Mac Pro? Will it work?

My 2008 Mac Pro has been replaced for daily work by a Mac mini. But I still play windows games on the Mac Pro. In fact it only has one hard drive in it, that has Win 7 on it. The card in it now is a Radeon HD4870 series, and is showing its age.

Can I just put a GTX970 or similar in it?, assuming the power connections can be sorted. I'd love to give it a new lease of life, than spend a ton of cash on building a new windows gaming machine. Can it be done?

I'n not looking for a card to work in OSX, which the sticky thread alludes to. I only need it to work in windows. Hence my question.

I've had no issues with a Nvidia GTX 650 and ATI Radeon 5770 ... both being "PC" cards in my 08 mac pro.

Since booting in windows will run the bios emulation I don't think that you will have any issues with any card as long as the Mac has enough power to feed the card.

Thank you. I shall try the card in it and if it doesn't work, then I'll just build a new rig.
