Could the heat have anything to do with the fact that I am running dual 1900 x 1080 screens off of this one card?

Well your CPU's max temp isn't really the problem here- its your Video Card's temperature.
I don't know how long you have had the system, but try taking compressed air and cleaning out the heatsink and fan on the video card. Also try repositioning case fans. You may want to look at a new HSF for your video card.
Before we do that; there are ways to check. First off, keep your case open and try and keep the space around your video card free of anything. Run Futuremark or whatever benchmark utility you want and keep an eye on the temperatures. Try and keep it below 75C and see if it shuts down then (I doubt it will).
As for the dual monitors - well sure it contributes. Instead of having to render an image to fit on 1920x1080 pixels, it has to render double that. While you are at your desktop it really isn't a big issue; however, when you go into a game, you then have to render a TON more. Now disconnecting one of the screens might help temperatures, but the mere fact that your card reaches 75C in 30 seconds means your card is STARVED of cool air. If worse comes to worse, try and aim a wall fan at the card for now.

I will take pics tonight and post them. I did a very very clean cable install. The video card is the only thing I have in any of the slots. Although, I wonder if the southbridge heatsink has anything to do with this:

Jeez - that is stupidly hot. Whoever the chief architect was should be let go IMO!
If the screen goes blank after 30 seconds of GPU load and then 113 seconds of lighter GPU load though, it still has to be a problem with the GPU in my mind.

As long as failure rates are low, I don't see it as being a problem.

Sure it isn't a problem but it is horrible design/engineering. That much heat means a ton of power is being used. Given that it is a 4870 and isn't the fastest thing on the planet, it shouldn't be wasting that much power (be it by Transistor Leakage or otherwise).
The 4870 is a 150W part capable of 1200 Gflops (according to wikipedia). Intel's i7 chips are limited to well under 100 Gflops.
GPU's do a shit-ton more work than they get credit for, and the power has to come from somewhere. There is no free lunch.

I was more referring to the fact that the Nvidia equivalent processes just as much while using less power. I hate having a leaf blower (Ah fun to reminisce about the Geforce FX) running wild in my case.

OP - I would still check and see when the Video Card shuts down (By when I mean at what temperature). If it is a consistent 75C, it could be a problem with the card's fan controller or something. If there is a way you can throw a test card in there instead and run Futuremark - you can really isolate whether it is the graphics card or not.

My 4890 hits low 80s when Folding. 9800GTX+ hits Mid 70s. Under load, that's not an unusual temperature.
Unless there's a localized hotspot, I don't think the 75C temp is necessarily what's causing the crashes.
