The 3000's hard disk subsystem runs over 4x the speed of the best A2000 hard disk controllers. In reality, you don't notice that difference in terms of disk performance, since even the best drives around don't go anywhere near that fast (neither does SCSI itself). What you get is more CPU time during disk activity. While on a 2000, you get somewhere between 0% and 50% of the CPU time free during heavy disk activity, on a 3000 you get about 95% of the CPU time free, both with a typical SCSI hard disk. > 2.

You do get 32 bit wide Chip RAM on the A3000, which makes graphic stuff go faster. Other than a slight increase in Intuition "snappiness", you won't notice much difference if you're mainly interested in programming and other non-graphic stuff. > > 3.

The 1950 isn't bad, and there are even better ones from other companies for more money. Watch out, though, because high-end monitors of this type may have a lower limit of 31kHz horizontal rates. That works fine on an A3000 for most things, but you can't do real video work or use the titling mode (I think the software folks call it SuperHiRes, the 1280x400 NTSC display). >* Tom Hayko * Call The Amiga Showroom * -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "That's me in the corner, that's me in the spotlight" -R.E.M.
