i agree, 3dmark is a TERRIBLE way to benchmark anything. and as for a gig of ram being useless...i can't wait to be able to run photoshop, autocad, opera, msn, icq, msword, powerstrip, norton antivirus, tv-wonder software, etc etc ALL AT ONCE.
if you want to bench realisitically, use something that really stresses the memory. try turning the cache in ut2003 up to 512mb, textures at max, all details at max. that might work out better. or you could try to bench doom3 if that's possible.
i'm not thread crapping here, just giving constructive criticism.
