Luxg, I have bad news. The test of Crysis didn't last long. I loaded up GPUZ's newest version that measures additional temps and then started Crysis. The CPU temp went up a few degrees which I expected. But what I didn't expect is the VDDC Slave #1, #2 and #3 temps to go through the roof.
I saw
145 DEGREES CELSIUS! 
This high temp was similar on all 3 slaves. I know they are supposed to get hot, but that's ridiculous. So, I shut things down and pulled the card. Thanks to Wizard I noticed from the picture he posted that I had forgotten to sink the tiny but very hot VDDC Slaves, (3 of them). So, I pulled out some spare sinks and installed them.
I haven't run Crysis again, yet. I did run COD4 and noticed that the VDDC Slaves were around 80-85C under load. I guess that's an improvement, but I won't know for sure until I run Crysis. I'm running the 120mm fan mounted to the cooler but that is obviously not enough to keep the VDDC's at least half-way cooled down. By the way, the DISPIO, MEMIO and SHADERCORE readings were from 5 to 9 degrees Celsius warmer than the GPU temp. Certainly not near the Slave temps.
Are these slaves supposed to get that hot?
I am tempted to pull the card again and re-think the sinking process I used and see if I can figure out a way to cool it down. I also will re-seat the cooler once again. Simply having a cool GPU doesn't mean your heat problems are all solved, at least with the 4870.
I think I hear my phone ringing. I think it's NVIDIA calling.
