hey everyone. I trying to chose what size of hard drive should i get. i just bought a 160GB SATA 3Gb s Hard Drive 8MB 7200RPM 3.5IN Caviar Blue and stalled it in a DELL 4600 DIMENSION. Now i have another DELL 4600. Should i get another 160GB SATA 3Gb s Hard Drive 8MB 7200RPM 3.5IN Caviar Blue or should i get a 320GB SATA 3Gb s Hard Drive 8MB IntelliPower 3.5IN WD AV-GP. Right now it has a 80GB hard drive. this is computer will be used for making cds and dvds. thanks for the help
