Test Setup And Benchmarks
We tested all of the cards in today's story with each company's latest beta drivers: Catalyst 14.1 beta 6 from AMD and 334.67 beta from Nvidia, however the new GeForce GTX 750 Ti required a special 334.69 beta driver. We used medium- to high-detail settings at 1920x1080 to give the GeForce GTX 750 Ti and its competition a realistic workload, which should strike a good balance between image quality and performance for this class of card.

We've almost completely eliminated mechanical storage in the lab, and instead lean on solid-state drives to alleviate I/O-related bottlenecks. Samsung sent all of our offices 256 GB 840 Pros, so we standardize on these exceptional SSDs.
Naturally, discrete graphics cards require a substantial amount of stable power, so XFX sent along its PRO850W 80 PLUS Bronze-certified power supply. This modular PSU employs a single +12 V rail rated for 70 A. XFX claims that this unit provides 850 W of continuous power (not peak) at 50 degrees Celsius (a higher temperature than you'll find inside most enclosures).
