Testing notes

We've put in our shiny FX-8150 chip and looked at the Gigabyte in relation to the ASUS 990FX Crosshair V Formula motherboard. While we already have stock-clocked numbers for the ASUS board, we feel as if there's little point in showing you just how fast the Gigabyte UD7 is at basic speeds. Rather, potential purchasers will look to use such a board as a base for really pushing the chip.

Accordingly, the Gigabyte has been benchmarked with the FX chip running at 4.7GHz/1.42V, in line with the also-overclocked ASUS, and we'll determine just which is the better board for the enthusiast. You'll see three sets of results in upcoming graphs: one for the stock-clocked ASUS and two for the overclocked Gigabyte and ASUS boards.
