Test Setup And Benchmarks
We'll compare the Radeon R7 260 to a wide range of cards from $80 to $140; we want a good overview of the budget-oriented marketplace. All of our benchmarks are run at 1920x1080 to show how AMD's latest handles Full HD.

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).
