Left 4 Dead was tested at 2560×1600 and 1920×1200 with 8x anti-aliasing and 16x anisotropic filtering. All game settings were set to their highest level.
The source engine doesn’t really stress these systems sufficiently to cause any issues regardless of the settings used. The Nehalam EP wins all the benchmarks but the differences are not really noticeable.
Last month Intel launched their Z97 chipset, essentially an evolution of Z87, which in many cases brought new features such as SATA Express and M.2 compatibility to the mainstream desktop market. There was of course no new CPU at that time with the existing socket 1150 processors working without issue in the new boards. Since then though Intel launched (along with some lower spec models) the Core i7-4790K, a model which sits at the top of their mainstream platform. Today we see how it compares to various other models when installed on Gigabytes Z97X Gaming 5 and paired with PowerColors new dual core 290X Devil 13.
