I have a 1800+ T-bred B that I know will do 2.4ghz easy, but its sitting in a ECS K7S5A pro @ 2.1ghz. All that potential is not taken advantage of. I finally realized how slow my 2.4ghz Pentium 4 is compared to this athlon xp i already have. I plan on getting a better motherboard for this chip to replace my pentium 4 in my main rig. I just need the faster choice of the two chipsets and I don't really care which one offers better sound codec chips since I plan on using my SB Live!. Also, I do have two 256mb samsung dimms that can definately be used for dual channel ddr400. I also know that Kt600 boards are cheaper, but I plan on getting that $53 Biostar Nforce 2 motherboard from newegg. Thanks.
