Radeon HD 5870: How much faster than the 5770 in 2010 Mac Pro?

Here's another twist.

Radeon HD 5870 and 5770 in the 2006 Mac Pro versus four older GPUs:

Thanks barefeats.

Any plans to run some tests in Windows on the 2006 Mac Pro? I'd be surprised if the 5870 didn't outperform the 5770 significantly in Windows.

Also, did you check whether the 5870 worked with the MP11.005C.B08 Boot ROM?

Indeed, thanks for this round of testing.

I have a Mac Pro 2,1 and want to get a 5870 purely for FFXIV in Windows, but be able to take advantage of it in Mac OS X as well. Good to see how much it smokes my x1900 XT.

Apple at this point is 2-3 weeks for a 4870 @349, 2-4 for a 5770 @249, and still no data on the 5870 @449. Guess I'm gonna miss the launch while waiting

X-Plane 9.6.1 at 1920x1200:
5870 = 83 fps
5770 = 80 fps

I built a Core i7 Hackintosh running Snow Leopard 10.6.4, 6 GB RAM, with a GTS 250, 1 GB graphics memory, primarily to run X-Plane 9. With all settings at Max, driving a 23 inch HD monitor at 1920 X 1080, my FPS is all over the place: well over 300 fps in sparse areas and sometimes dips as low as 30 fps for a few seconds, in the largest cities.

How did you arrive at the 83 fps when the rate changes constantly?

I used the Gigabyte LGA 1366 mobo so that I can switch out the 4 core processor to a 6 core processor when they come down in price. By then, X-Plane 10 should be out which will take full advantage of the powerful processors and video cards.

On a whim, I bought MS FSX with the intention of installing XP Pro, but the mobo would not let XP install. Since I had already purchased FSX, I bought Windows 7 64 bit. After running FSX a few times, I find that I rarely use it since I really like X-Plane.
