will a ATI5870 work in a Mac Pro 1,1?

Do I need to flash a Mac Pro 1,1 to get a ATI5870 to work?
thanks

It should work, just make sure you are running Lion, although Snow Leopard might have the drivers also, I'm not sure.

It will work, but I've previously seen that on a 1,1 the performance improvement over a 5770 is very small, unless that has changed.

Yea the difference is huge, when I had my 1,1 It had a 7300 gt and was running a 30" and a second 1080P display and then when I got the 5,1 with the 5770 the difference was amazing, can't wait till I out a GTX 670 tho

Ah, ok. I was thinking if you were buying it, it might be worth it to save the money and get a 5770, but if you've already got one...

There's night and day performance difference between these 2 even in 1,1.
But this is strictly app dependent. I've used number of different GPUs with my 1,1 and it's always like that. CPU limited ones will never show an improvement.

Let me quote wise words from another thread:
