I'm building a PC for the very first time. I just ordered a soyo dragon plus, an Athlon XP1600, and a Maxtor DiamondMax Plus Ultra ATA/133 40GB HD. I freaked out when I realized that the dragon plus only supports up to Ultra ATA/100. I thought that I was going to have to return my HD to googlegear.com and pay a 15% restocking fee!! But then I learned that this HD will work with my motherboard, but will only support transfer rates of 100 MB/s. My question is, should I buy a controller card that supports Ultra ATA/133 and attach my HD to that? Will that make the transfer rate faster, even though my motherboard doesn't support ATA/133? If so, how much should I spend? I believe that I saw one for 50 bucks. Thanks
