i play 5 on a laptop works fine, ive turned the sound off which i guess helps abit but i didnt do this for performance i did it becuase the sounds of 5 people doing things over and over got annoying.

your laptops spec is simular to mine i have a faster processor 2.33 T7600, 2 GB memory, NVIDIA GeForce Go 7950 GTX 512MB x2

but the only sure way you can check mate is to get 5 trial accounts on it and give it a try.

i think you would want the to put the 2 19 inch screens together the laptop monitor at 15.4 is way too small, my very messy screen (just one screen i over lap the wow windows) can be seen in screenshots part of this forum, people go for slit across 2 screens but i like how mine is used to it now and very easy to swap between characters.

hope this helps you get started what classes have you decided to try first?
