post #1 of 4
Thread Starter 
Is it possible to run with quadfire 4x7970 with pcie 2.1 or do i need pcie 3.0?

sorry for my English, thanks

Yes, it is likely possible. As for whether or not you are going to see a big performance drop because of 2.1, you'd have to wait until the release of these cards to get benchmarks to find out like the rest of us.

do you have a 7970? and yes it will be possible, i doubt anyone will see much benefit with PCi-E 3.0 from next gen GPUs until the next next gen, first gen PCi-E 3.0 devices aren't even out yet, and the current gen can't even take advantage of 16x PCI-E 2.0
