I'm running them in surround on my new build with mixed results . Strangely , they lowered my score on the Ice Storm section , from 72634 w/the 760s on my 780i board& q9550 to 26038 ! Other 2 portions are higher by almost 700 points . When gaming I started getting stuttering where none was before and the 2nd gpu was carrying most of the load . I could not go back to the previous driver (335.23) do to surround not "seeing" my second card but windows did . Numerous clean uninstalls & reinstalls didn't help . Finally went back to the 338.88 drivers and games play fine now , but the 3DMark score is still low.

Curious why anyone on any PC with any dedicated video runs a mobile benchmark, meant for tablets and cell phones.......... Try a benchmark meant for computers, then see how results compare.

Driver was the problem...specifically PhysX was not installing/uninstalling properly . Noticed there was no PhysX driver listed in Programs and Features  , yet NVidia control panel showed latest PhysX driver loaded . Used stand-alone PhysX installer to remove PhysX & then reinstalled PhysX . Now my games are running smooth again & my benchmarks are now (way) higher .

I downloaded the latest 3DMark last night . The original had only 3 benchmarks & 3 demos , had to run all of them on the free version (no mobile) . Now the latest one says it's also for mobile (didn't say that before) . So we're both right ! When I ran the sky diver benchmark the demo looked amazing . Loved the "physics" on the diver's chest ... LOL . But when the benchmark ran the first test my screen went black but it was running the test (counter stated up). The last one popped in & out . But it wouldn't give me a score - said my drivers wasn't valid . Same driver I ran my other 3 benchmarks & says they're ok . Must be a glitch ... oh well .

I will give Sky Diver a try, as I only have my 750Ti in the system right now.  You have piqued my interest with the Physics on the chest thing...  now I have to know :-)

Anyone had any Black screen problems like myself with the 337.88 WHQL Drivers so far??? Can be Web Browsing or watching a Vid or watching TV via a net feed and bam the screen goes BLACK!!
The temps i constantly watch on my no 2 screen, have my Precision-X Fan profile set up and the Temps are under 50c most of the time!
 
Have to press the reset button on the PC and everything is fine and dandy again, then a few days later on same thing again!! Never had this with 337.50 Beta Drivers just wonder if this is the Driver problem here!!
 
Hope its not my 780 TI going down!!
