Should I spend an extra $15 on a 32 bit notebook network card instead of 16 bit? Speedwise, they say it's faster, but I think that's just more hype than anything. The 16 bit card looks like an older model so it probably consumes more power than the 32. Any comments on real world performance of the two cards? A little more money for the newest, or save some money and go for something a little older?
