GTX 780ti black edition bottleneck

post #1 of 5
Thread Starter 
Will this nVidia stuff be bottlenecked by x16 PCIe 1.x speed? What about x16 PCIe 2.x speed?
If I quadfire will I see a difference in having card 1 in PCIe 2 x16, gfx card 2in PCIe 2 x16, card 3 in PCIe 1 x4, card 4 in PCIe 1 x4?

One, it will not bottleneck a PCI-E 2.0 x16. However, there is a possibility you would bottleneck the card in PCI-E 2.0 x8x8.
Two. It would be quad-sli not quadfire.
Three. You cannot run quad sli or any form of SLI in a PCI-E x4 slot.

Ahh, yes. I stil remember my ATi days.

Do you think it would be worth waiting for the cracked x16 firmwarez to be released before getting one? This card will be going into a Mac Pro.

I'm not positive what you mean. IIRC you have to flash a specific firmware in order to use it on a Mac. I haven't worked with Macs much, and especially not with adding an aftermarket card. You will definitely want to wait until there is compatibility, though.

It is not nessesary to flash, but it allows the boot screen, EFI acsess, PCIe 2.x, and the boot manager. If those things aren't needed, then the card can just be popped in.
