You will be okay with x16/x4 crossfire. You'll only see a 4-5% performance penalty with x4.

Some motherboard manufacturers are offering a third PCI-Express x16 slot that is electrically x4. The results show that the performance drop isn't as bad as one would imagine, so we will green-signal installing a third accelerator for some 3-way ATI CrossfireX action, or 2-way CrossfireX on entry-level Intel P55 motherboards with the second x16 slot electrically x4 (running in 1.0 mode).
