"...Gnome is right. Go with XP and the 3400, although I would recommend 2gb of ram. If you multitask while trading it is not hard to use up 1gb, and it wont cost you much to go to 2gb.
Agree about "not costing much to go to 2GB [RAM]"... however and while it's conventional wisdom "if you multitask while trading, it is not hard to use up 1GB..." is questionable.
The reason I say that is because I like the rest of you have multiple programs running during trading... in my case it includes a TV tuner card, one and sometimes 2 browsers, and MS Word.
WinXP is good about "paging out" lower priority functions such that on my 2GB RAM rig, and when it's using 850MB of Commit Charge, I still have 1.5G of Physical Memory Available. Therefore, 1GB is plenty and the 2nd 1 GB is really a waste. I suspect most traders' experience is similar. That's why I suggested "checking during the day to see how much Physical Memory is Available" so that one might know whether 2GB is actually necessary.
I suppose one might run Photoshop while trading.. and in that case more RAM is justified. Or, certain trading apps might actually use the extra GB of RAM... but that might not be as likely as most of us think.
