Anyone running two cards PCI-E x16 + PCI-E x4 in Crossfire mode?

Can you share your 3DMark11 scores? Or you findings in general?

My Gigabyte mobo only have this configuration and I wondering if it's worth it for say Crysis 3 level of graphics.

Thinking of two 7770 cards.

I would recommend a single mid/high range GPU over two low/mid range ones no matter the circumstances. The 7770's will bottleneck you with 1Gb video ram as well as a 128 bit memory bus. I would go for a 7870 for about the same price. Gives you the same or marginally better performance, but with double the VRAM and no crossfire woes.

I'd grab this card when it's back in stock. It's actually a crippled Tahiti core, and you should be able to easily OC it to 7950 speed or more.
