Well, my gf3 ti200 clocked at gf3ti500 levels would love a new mobie and cpu. I currently have an athlon 200mhz fsb cpu @ 1391 mhz on the old kt-133 with pc-133 sdram. I was wondering if i should go up for the new northwood coupled with pc 3300 ddr mem and a sis 645 mobie, or a kt-266a or kt-333 mobie with a 1700 + xp athlon? Any ideas, or should i wait for the thouroughbreds? NAy ideas on what is the best p4 mobie out there, not interested in the i850, but more deciding what's the best, sis 645 or i845d or p4x266a or should i wait for the sis 645dx? Thanks.
