same reaction here, nekofrog.
there's one hole in that argument, pez.
32-bit: up to approx. 3.5 gigs (due to video ram, system space reservations)
64-bit: up to 127.5 gigs of ram (due to the same reasons).
128-bit: way more.
there's no way in hell consumer systems are going to overrun 128 gigs of ram any time soon. 128-bit will be for super-machines - not for the commercial market. 64-bit should have been the standard when vista came out, all told - the x86 architecture was useless with the high memory demands that vista puts on it.
