Read this artical: http://www.tomshardware.com/reviews/p55-pci-express-sca... Essentially, with two 5870's, running at x4, you lose performance, but two 5870's running at x8 hardly are effected. Two 5770's are about the same speed as one 5870. Things might not scale exactly so simply, there is some reason to believe they would perform ok. Maziar January 14, 2010 8:28:00 AM Yes you can run but as bystander said,with 4x you will lose performance,dual 8x and dual 16x are good options but 16x4x performs worse than both and isn't recommended for CrossFiring Related resources Crossfire HD7870 x8 questions? - Forum 6950 Crossfire Issues - Forum Asus 660ti DCU2 SLI, 680 DCU2 TOP or 7970 Matrix - Forum 5870 in crossfire - Forum [Solved] Crossfire 4770 vs. Faster GPU - Forum Can't find your answer ?
