Just setup new open box XPS 8930 16GB I7-8700 machine that I got for $499 (it came out last year).
It replaces a Sandy Bridge i7-2600s (lower power version).
BI was running at about 25% of cpu consuming about 85 watts on the Kill-O-Watt on the Sandy Bridge machine.
The new machine with Intel acceleration checked in the BI settings sits at 14% cpu 4% gpu at 65 watts.
Now if I select CUDA, the cpu drops to 6%. Awesome, right? But not actually because the GPU goes from 4% to 12% and more importantly, the power consumption jumps from 63 watts to 70 watts.
So if you NEED CUDA in a case where where you're CPU bound, it's a great thing, but overall it produces takes more energy and produces more heat.
