2-3 way crossfire question - Page 2

post #11 of 13
As Ken said, if you are running resolutions of 2560X1600 or lower 16x/8x/8x will be fine. There should be no noticeable difference. If you are running eyefinity for example 5760x1080 than I think 16x/16x/8x would be better.

What are you all going on about? NF200 chips are used on heaps of boards, pretty much every 4 way sli certified board would have a NF200 chip unless its a cheap board. The EVGA X58 classified's, X79 classifieds and the SR-2 have NF200 chips.

For example my Classy 4way sli has two NF200 chips, i7 900 series have 36 pcie lanes, running 3way crossfire and physx i had four cards in. I had 16x16x16x8 bandwidth. NF200 chips add more PCI-E lanes and hence add bandwidth, the trade off is the NF200 chips add higher PCI-E latancy.

Its like how X79 only supports 4 sata3 ports, so a lot of boards have marval controllers to add another 4 sata3 ports or so, they have the same bandwidth as the intel ports but a higher latancy
