Nvidia's GeForce GTX 750 Ti falls in between the GTX 650 Ti Boost and Radeon R7 260X in our benchmark sequence.
Frame time variance spikes in a handful of cases. Experientially, though, the game is smooth, so we're not coming down hard on any of these results.
I'm pretty sure you meant to type "video cards" on page one there. Cheers.
Don't take this as fact, but the drivers look newer for the Zotac card than the others, possibly just a bug with the older drivers? The cards are advertised as having 640 shaders anyway.
Also weird, the GPU-Z screenshot is taken with Windows 8, whereas the Gigabyte and MSI cards are on Windows 7. The mystery continues...
