having built and overclocked AMD systems, I'm looking to do the same with a P4 system.Looking at 2.26 Northwood,ATA 133,533 fsb.The boards that meet my need are about $80-$120 for ddr support and $160 and up for rambus supported board.My question is: will rambus performance be worth the extra money put into the board and memory? Checked search engines and can't find anything that clearly tells me. What's your opinion/experience ? thanks in advance....
