Mac pro 5870 question

[tpavur]

As we all know the main focus for mac's is not gaming, however with my Mac pro recently arriving with the 3.2 quad and a 5870 GPU; what kind of gaming performance increase will I notice vs my 2010 iMac i7 with the mobility GPU card in it? I really don't want to disrespect any of you guys by asking this question as this is not why I bought my Mac Pro, and this is not a "gaming" forum, however I do game a little and I could not find any benchmarks that put the two side by side.

Let's use black ops, and maybe crysis as a means for making a comparison and any other key games you can think of, btw all gaimg is done via boot camp with windows 7 ult.

With my 5870 I've been able to crank SC2 and Portal up to the very max on every setting without any lag (and that's on OS X.)

No idea how it compares to the iMac, but the short answer is "It will run almost all the games out right now perfectly."

Really depends on the res you play at now.
As the resolution gets larger the 5870 pulls ahead in a bigger way.
Couldn't find any DX10 benches but here is Battlefield BC 2 (1920x1200, 4AA, 8AF, High Quality, DX10)
5750: 25.6 FPS
5870: 52.3 FPS

3D Mark 06:
iMac 5750: 15344
5870: 23640

3D Mark11 Enthusiast settings:
FPS:
5750: 12.44
5870: 27.68

I don't have any problems playing anything at my 1680x1050 res. Including Metro 2033 (Much heavier than Crysis). I play Crysis maxed with 4xAA the only exception.

I max SC2 with around 33fps at 1920x1080.

Mac Pro 8-core 2.26

Portal 2 on my 2010 with 5870 plays at 2560x1440 perfectly smoothly on the default graphics which, while not the highest in terms of AA, are very good indeed.

I also noticed that Portal 2 doesn't cause the fans to spin up as much as the old Portal did.
