Performance in Grid 2 scales opposite of Battlefield 4, favoring the GeForce GTX 780-based machine in six out of eight tests, and switching over to last quarter's configuration at the highest two settings. That box with the Radeon R9 290s in it appeared more processor-bound though, and we've noticed similar CPU-dependencies from AMD graphics cards in the past.


The current build’s GeForce GTX 780 cards in SLI make a clean sweep of Arma 3, contributing to an overall gaming lead of approximately 12%. Can the older machine and its hexa-core processor catch back up in the rest of our benchmark set, though?

1.) Start the system, wait for all processes to load, take a measurement (Active, but idle)
2.) Load the CPU using eight thread of AVX-optimized Prime95, take a reading (CPU Load).
3.) Load GPUs with 3DMark 11 Test 1 in loop, take max reading as it heats up (GPU Load).
4.) Load both applications (CPU+GPU Load).
The "math problem" is that any program used to fully load the GPU also partly loads the CPU. So when test 4 is Prime95+3DMark, Prime95 can only use whatever CPU resources are left with 3DMark running.
So the most accurate system power reading is with "CPU+GPU Load" applied. The system measurement for "CPU Load" still includes the power of an idle GPU. And the system power measurement for "GPU Load" still includes the amount of CPU energy it takes to run the GPU's test application.
Power supplies of greater capacity and similar reliability at this price tend to be lower-efficiency units. And we like efficiency too.

Very much appreciated and satisfying answer.
Thanks Crashman

Wondering how much of a difference would non-reference cards make. Obviously, CPU cooler and RAM could be different, BR drive optional, storage drive as well.
Shouldn't that be DDR3-1866?
my fix is get a 700gb ssd, 780ti no sli problems, and a i5 4670, this is a much better gaming pc, and can go quiet build.
