my vote goes to the 3000 for productivity and 1200 for everything else. ive owned both. the 1200 had great tv output but looked like crap on monitor even multisync ones. the 4000 would be similar i assume
the scan doubler flicker fixer in the 3000 is so good it is tough to ignore. just search the postings for people begging for one for their 1200s or 4000s
the big thing ive had against the 4000(t) is that it is so freaking expensive. for a base 4000(t) you can usually get a 3000(t) with a video card negating some of the loss of aga. many games had aga and ecs versions not all but many
one plus for the 1200 was compatability though. it ran everything i threw at it. the 3000 wouldnt run some stuff including some games
