Im planing to use this with 6 280x but if is possible to use 7 the i will use 1 more.

Its possible?

The motherboard you picked is an excellent choice for GPU mining. Running 7 cards, your biggest challenge is going to be power. The 280x runs at ~250watts when undervolted properly, so 7x250=1750 watts. Add another 200 watts for system overhead and you're at almost 2,000 watts. If you're on a 110v 15a home circuit, you're going to be flipping switches or blowing fuses. If you're on a 20 or 30 amp, you should be fine. You might find additional helpful information in the 6 GPU guide: http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/

yes, my old rig have 5 cards, i thank 7 are the same
pre-caution: you need some pcie1x extensions and pcie1x-16x extensions(WITH MOLEX)
otherwise, your mb 5volts pcb trace will overcurrent and burnt
