It's the same old story, I'm building a new rig, and I want to overclock it, but I don't know what format/motherboard hold the greatest possibilities. I have heard (actually read, on THG) that when greatly overclocked, say, 2.8 -3 GHz, DDR loses it's efficiency, and RDRAM is the only way P4s can maintain a very high performance benefit. However, I have also heard that RDRam is a very finicky overclocker. I have narrowed my search down (perhaps wrongly, please let me know) to the Gigabyte 8IRXP and the Abit TH7-II. I don't really want to wait for 133 MHz FSB to come around, so if you guys could recommend alternatives, give advice on the RD-RAM vs. DDR-Ram issue, and maybe share experiences/achievements with either of these motherboards, I would be much obliged.
