NVIDIA 337.50 Driver Comparison @ OCC
 

"From looking at the results, as long as you are not GPU bound, it seems as though the 337.50 drivers do offer some upside in most of the games tested. Star Swarm sees a 25% boost on the GTX 770 and the GTX 780 Ti is closer to 30%, exceeding the "up to" 21% stated on the release notes. In BF4 the single card gains were minimal, as were the gains at 5760x1080. However when you run the SLI numbers at 1920x1080 you get an easy 5% to 6% boost. Metro: Last Light, much like BF4, shows minimal gains at 5760x1080, but shows promise in both the single and SLI testing at 1920x1080, with gains as high as 8%. The greatest performance boost in Batman: Arkham Origins bucked the trend of being GPU bound with a pair of GTX 780 Ti in SLI by bringing home a 10% boost in performance. Far Cry 3 shows gains in almost every test; the largest gains coming from the SLI configurations at 1920x1080 with the GTX 770s delivering a 7% boost and the GTX 780 Tis delivering a 4% boost using the new driver."
