Man I tried an Experiment tonight and boy was it a failure, I just kept on opening up table after table after table, after table, and I must say that eventually I hit a number of tables which I couldn't fit it all on my screen at 1 time so I then had to force myself to do it and play like that , damn i had hard time keeping track and focuse of what i'm doing
depends on what you play, what level, why you play.
personally, sng multi-tabling most of the times, not worthy in any other way at micro, low limits, especially if you want to get back something from leaderboard races, rakebacks...
8-12 tables fit perfectly on 1 screen, easy to handle. never had the equipments - one day i will - but the regulars use 2-4 screens, monitors and play 20-30+ in the same time. similar like cg...
better $/hour rate... if you play for fun, it is not a good option, but even playing tourneys, 1-2 tables are really boring, put on tilt faster than playing 6-8+ tourneys in the same time...
