A couple of mobos I am looking at support dual channel memory. I will go with 1G.
Two sticks of name brand PC 3200 DDR 512MB can be found around $150-160. Dual dual channel memory, PC 3200 DDR (2x512MB) ranges in price from ~$170 for name brand 'value' lines to ~$400 bucks for top lines.
In FS terms, what difference can one expect from the low to high end options?
