Hi guys, Thanks a lot for your valuable input. I´ve heard that GNS3 with Linux runs a lot better than in any Windows based OS. Actually a friend ran 6 routers with just 1 Gb of RAM (Linux based OS) using all the feature GNS3/dynamips has to reduce the memory/CPU consumption, so I´ll go for my CORE 2 DUO 2.66Ghz with 6Gb of RAM and will make a partition for Ubuntu 9.0.4 to run GNS3 there.
Thanks a lot!

I can run up to 14 routers in my setup. A 64 bits system will not give you some better performance, just will let you address more memory.
