Will PCIE 2.0 x16,x4 crossfire work? Tags: Radeon Performance Crossfire Motherboards Graphics Last response: August 13, 2012 8:36 AM in Graphics & Displays Share N11Ckk123472 August 13, 2012 8:30:57 AM I have a motherboard that supports crossfire, but only at 16x, 4x...How much of a performance hit will I get? I currently have a MSI 6850 cyclone edition, and money is tight so I can't really replace it with a beast single gpu, so I'd rather xfire it. Would the low bandwidth matter, and if so how much would a performance hit will i get? Will it make the extra 6850 worthless? I really want personal experience, not just a bunch of benchmarks, but those would also be appreciated.
