Re: gns3

and I would add:

if you cannot afford to buy a quite enough powerful laptop for gns3 you can
always try some cloud services..
I am using amazon aws ec2 and I'm using the "medium" size image.. (means 4
giga ram + Xeon CPU @2.4Ghz).
This is very cheap (0,23$/h) and you pay only when you use it!.
Maybe there are even cheaper services out there in the cloud..

in this way you can try gns3 there before to buy a laptop or instead to buy
a home server just for gns3 :)
