multiple games concurrently....another "win $$/hr" question

[trojanFan]

i've seen players on party playing in multiple SNG's at the same time...obviously it's one way to increase your $$/hr.

however, the obvious drawback would be a suffering quality of play. but i know that people do it.

i'm asking the experts...are you really able to do it and not substantially affect your skills? if yes, then how?

2 monitors? sit out of the beginning rounds of one tourney while in the heat of the finals at another?

thanks!
