easily, you won't break 750w at peak and silverstone has great PSU

Also which would be a better CrossfireX setup:

5970's or 6970's

6970's would be a better setup. 6xxx scaling is world's better than the 5970's.
Quad-scaling in general isn't good.

You can CF two 5970's I have seen it done.

I don't think you can crossfire two 5970's - at least without an headache.

I have Dual 4 GIG Black Edition 5970's Crossfired - so yes. It can be done. I also do have the Silverstone 1500 Watt Power Supply though. You're looking at at least a 1250 watt PSU to Crossfire these.

By the way - 1250 Watt is the Minimum Recommended Wattage to do so. With some searching, you can find it on the XFX or AMD site, I forget which I saw it at.
