I'm going to be buying a GeForce2 MX pretty soon and I've decided to buy the Guillemot (is that spelled right?) brand since it seems a bit above average. One thing, though.. The card with 7ns memory is $108 and the one with 5.5ns (or something like that) is $149.. Is the 5.5ns memory really work the extra money? Or will I hardly tell a difference on my K6-3 400MHz?
