Back at CES (during the G1-Killer launch) we were shown something pretty special; besides the G1 we mean. While Tim Handley was telling us about the virtues of the G1-Killer line-up, he flashed us a picture of a new board that was still under development. This was an early image of the X58A-OC. The concept was a streamlined product intended just for overclocking and performance.
You still get audio and LAN on the board, but for the most part the extras that are on many boards are gone. Of course, with the items removed other pieces have been dropped in to handle the extra voltage and current load from pushing the CPU and multiple GPUs to extremes. Despite the lack of all of the "extra" features, the price is still $380 from Newegg.com.
