I would suggest minimum 1G ram.
Make sure the MB you get has Dual Channel.
Get the Best Video card you can afford. ( MOST IMPORTANT)
get the 6800 Ultra OC with the 256MB DDR II or the equiv ATI
Ram and video card make or break all online games.
Go with Raid set up if you can, load times will be faster.
I have XP 2800
1Gig Dual Channel DDR2700
GF FX 5700 256MB
80Gig WD 8MB cashe
And I can play EQ 2 very well, not much lag with stuff set on High.
I did turn off shadows and went very mild on Floral.
Other than that, everyone on high settings, have a few things on very high.
I do wish for more tho. So beat my system if you want EQ2 to run ultra smoothe.
My plans for upgrading will be very soon and here is what I am going with.
1st: Evga Nvidia GF 6800 GT 256 bit. 256MB GDDR3
2nd: Two 1Gig sticks of DDR2-533 ram ( 240 pin ram)
3rd: AMD 64 3400+ socket 754 1MB L2 Cashe
I need to research which mobo. My hopes is Asus has a good 754 board.
if not I'll look at others.
