Main computer is a 3 GHz hyper threaded P4 with 2 GB of memory, plus 2 21" LCDs (not that that really matters). Hyper threading helps for multiple Java apps, so I recommend that.
I have a Celeron II 400 Mhz with 128 Meg RAM Windows 98 SE Usually run TWS + AmiBroker and Quote Tracker or one fo the two latter + Outlook Express
