i ordered it, hope it will be here soon. it's going to replace my old 1.42 ppc. i'll use it to recode my tv shows, movies and porn. any way... i saw it can handle 2g of ram in 2 sticks, then i saw 3g in 1+2 sticks, then some one told me it will handle 2x2 sticks but it will only show 3.2 or 3.7g. so... how much memory to buy?
