I have a 1200 with an 040 card. Its fast and brilliance is a wicked paint program for it.
I don't play games, never have the time with my other hobbies.
I will admit it is sitting in storage because my 060 3000T with a picasso II is just nicer but once I get around to ether uograding to an 060 for the 1200 or building a platform so I can have better cooling on the 040 I won't use it much.
Personally I enjoyed my 1200 more when it had a DKB 030 and scsi system.
