2 HD3870's with Dual Monitors BootCamp

[BenDew]

Hey Guys, I am looking to get a Mac Pro, and have 1 or 2 questions about graphics cards and dual monitors. I plan to use Bootcamp ( I play games in Windows) , and need something more powerful than a 8800GT. I am looking to get 2 3870's and run them in crossfire when I am in vista. My question is, Can I run these two cards solo in Leopard and crossfire for vista with dual monitors operating in both OS's without having to unplug or change any cabling between booting Leopard and vista. I also have a 8800 GTX I could run in windows, but I don't want to reach around and change monitor cables every time.

Also, would a 3870X2 run in Leopard? because then I could just have one card, 2 DVI ports, problem solved.

Thanks

The two mac 3870's work perfect for both - no unhooking necessary - I have three hooked up and Crossfire works fine in Vista64

Cant speak to the 3870x2 though I dont think anyone has one working atm in OS X I am fairly sure

Also I got a nice fps boost going from single 8800 to 3870 crossfire in windows gaming just fyi

So you have 3 3870's working in Crossfire in a Mac Pro? Is yours the Early 2008 or the older dual-dual core? I have an older generation and am thinking about 3 3870's if it will work.

And are all 3 of yours the Mac version?

Thanks.

Just two and its early 08 Mac Pro - not sure would be worth it to try 3 as then you're running into diminishing returns plus there's not enough x16 slots for that

Oh so you meant you have 3 monitors hooked up?

Yes , not three cards
