4850 crossfire @x16/x4 - Page 3

post #21 of 24
16 (PCIe 2.0) x 4 (PCIe 1.0) will suffer.

However, 16 (PCIe 2.0) x 4 (PCIe 2.0) offer virtually the same performance as 8x8 (PCIe 2.0).

2nd gpu: PCI-E x16 @ 4

Everest reads:
1st gpu : PCI Express 2.0 x16 @ x16
2nd gpu : PCI Express 2.0 x16 @ x4

AMD 870 has 22 PCIe 2.0 lanes. So I would go with Everest.

Which version of GPU-Z are you using?
