What prep do I need for a pair of 7950 cards? Which rig?

I bought an AM3+ Biostar TA970 (open-box, but it looked like the board was new, the I/O backplate was still in the plastic wrap) from Newegg recently, and I've got a pair of HIS 7950 cards arriving soon. Got DDR3 and an AM3 quad-core CPU.

Also have a rig with an ASRock 990FX Extreme4 (AM3+), 16GB DDR3-1600 (4x4GB), that currently has two HD4850 cards in it, and an Antec EarthWatts 650W. The PSU only has one 6-pin and one 6+2-pin.

Also have a PC P&C Silencer quad Red 750W PSU. Which I believe, has quad PCI-E power connectors. Unknown if they are 6-pin or 6+2-pin or 8-pin.

The 7950, according to the Newegg pictures, use two 6-pin connectors.

Thinking of getting into altcoin mining, at least for the winter season.

Also have one (and parts for another) G3258 rig, with Antec EarthWatts 500W PSUs (two 6-pin power connectors available). I could put the cards in seperate computers, in fact, I plan to do that eventually.

Just wondering what would be the best setup here.

Edit: If I get back into gaming at all, which would be better, one 7950 and a G3258 @ 3.8, or two 7950s and a 1045T @ 2.7, 3.0, or possibly 3.5 if I can get it clocked back up well?

Or should I look at getting a Haswell quad-core if I really wanted to get back into gaming? Would either the 1045T (for dual 7950s) or the G3258 (for single 7950) be OK for mining?
