I should clarify : He is currently using a laptop with an additional monitor, but would like to go to three monitors with the new build I am doing for him. Part of this build is the GTS250 I am giving to him.
The three monitors will not be used, for example, to play a game wherein everything is spanned across the 3 monitors. Primarily the usage is for a share trading platform wherein various program windows (e.g. ASX share prices, various stock prices, market indices etc. etc) can be undocked from the application and then positioned on any of the 3 monitors. In a nutshell, he is after more real-estate.
