I've noticed GNS3 mentioned a fair bit on here but up till now I've dismissed it in favour of real hardware.
I'm thinking of at least having a look at it - if my pc specs are ok. I've got a 2.4GHZ Dell with 768Mb RAM. I don't want to upgrade it as it's only used for web browsing and a bit of work from home stuff.
Will this run GNS3 ok? I wouldn't want to be restricted too much in terms of the topologies/labs I could create.
Or would I be best to stick to actual hardware routers?
