    Mac Pro 1,1 + HD5770 (bonus: HD7950 in 1,1 ... Power supply?

    Hi there, So here's the situation: I've got a Sapphire HD7950 that I pulled out of my MP 5,1. I intended to drop it into my older machine, a 1,1 running Snow Leopard that I use for media, but it seems the 7950 is just out of compatibility with the 1,1 tower - it runs, but I can only get 800x600...

    a couple of pre mod MacPro1,1 questions.

    Does anyone know if a Radeon HD5770 (MacPro1,1 w/Mavs) will support 2 mons on a combo of the DVI-I and mDP or both mDPs over 15 foot cables at 1920x1200 without a KVM or other extender? I would also be upgrading the procs to Xeon 5365s. Has anyone run GeekBench on a MacPro1,1 upgraded to Mavs...
