New to Dual/Multi Boxing,I have some questions.

Hello all.

To start off with,How many copies of World of Warcraft could i run on this computer? (

These are my speccs:

Core 2 Quad Q9540 @ 2.66 GHZ (Overclocked,aparently,From 2.00GHZ.)
4Gigs of DDR3 Ram.
8800 GT
Lost of space for the games themselves.

I have never run more than one copy of WoW before.
And i saw something in the wikipedia about system speccs,But i had no idea what they were (The items listed)
I will be leveling A paladin (Never played before) And if all goes well 3 (Hoping for 4,will go for it if my computer could handle it,also never played before)
So,at that,i am wondering what speccs i should be,Oh i will be using the RAF,Also wondering how to connect them properly so most of them (If not possibly all) Get the XP Boost.

Thanks if you can answer anyone of my questions.

4 copies will run fine on that setup.

4 gigs fine
6 gigs better
