Cool, glad you like it. Good choice on Windows 7 too. Windows 8 is a good base OS, too bad they had to ruin it by putting a useless interface over the top.
I'd just put the 7970 into your current rig and be happy for now. No need to let it sit on the sidelines.
If I am understanding what I am reading correctly, I can only have 2 monitors enabled through the 2 DVI/HDMI and I will have to get an active mini display port to HDMI adapter to do a third...is this correct?
If so can anyone link one that's definitely active and not passive?
Would anyone recommend this?

It's at Amazon for $89.99. 62 amps so it ought to run any 2 SLI/CF cards. Don't need it right now, this just looks like a good buy to hold for later. Unless anyone knows one just as good for even less than $90?
I also like that this price is not after rebate. I didn't look TOO hard but I only found one review so thought I'd ask.
I'd go with a Corsair CX750 for $90 ($80AR). It has the power you need, and modularity so you don't need to deal with cable clutter until you get the second 7970.
PSUs are not fine wines, they do not get better with age. $90 isn't a spectacular deal, certainly not worth taking a risk for. I'd wait until you have a need for the PSU before buying one.
The 7970 utilizes both a 6-pin and 8-pin (or 6+2 pin) power connector. That means it gets 300W at most. Your CPU is about 100W. The rest of your stuff together is roughly 25W at most(fans at 100% and HDDS/SSDs doing a huge write). 750W is enough, but if you desire safety, 850W is an option.
Personally, I don't know why you're trying to overclock CFX'd cards. They'll burn through any game and are hot/power hungry enough as is.
Well, I'd say you're right but I have another question. How much does a non-voltage increase OC increase power requirements? I bumped my 7970 from 925/1375 to 1075/1575 and no voltage and it seemed stable. But how much does that increase the power? In other words...is 750watts enough to OC two 7970s like that?
