<p>Nope, you're good to go. You don't even have to connect them all through PCI-e. With <em>cgminer</em>, you can set the settings uniquely for each card. You can use any kind of adapter that would normally bottleneck GPU performance. </p>

I'd assume that your weakest link would be the motherboard.

"You can use any kind of adapter that would normally bottleneck GPU performance" .. so using a PCIe x1 to PCIe x16 OR PCI to PCIe adapter would be ok?

<p>I have some 7950 and some R280, can I connect them both on one rig? Will it work normally? Or does system require all GPUs to be same?</p>

Can one rig run multiple different graphics cards?

Nope, you're good to go. You don't even have to connect them all through PCI-e. With *cgminer*, you can set the settings uniquely for each card. You can use any kind of adapter that would normally bottleneck GPU performance.
