ok here's the question I'm getting ready to build a new PC for myself as my ever increasing attempts to teach myself about computers.... BUT the question I really want to ask is.... does SCSI really justtify it's cost? I've heard from quite a few people that with ATA100/UDMA66 (is that the same thing? I'm not 100% sure myself) that the speeds are almost comparable and don't justify the cost..... any enlightenment would be of most use thank you... and no I'm not a big power user (unless you count spending hideous amounts of personal time on games)... I've just been saving a lot of pennies for the past year and a half and I've got a fair chunk of cash to blow away on my new toy..... any adivce would be welcome
