They have machines with up to 8 cores and 64gb of memory for a few dollars per hour. Drew Conway has an EC2 image that contains a lot of packages and libraries like R and NetworkX you would need for large network analysis:

This isn't for the faint of heart, but neither is doing an analysis of 50k or 66m nodes. I suspect there isn't much value in even attempting to visualize networks above 10k nodes.

I used to work with relatively small graphs (like 1209 nodes and 5555 edges) and even my netbook was good enough for them. But now I have data like 50 000 nodes and 1 000 000 edges which is really hard to draw and analyse on my current laptop with Intel Core i7 CPU M620 2.67 GHz, 4 GB RAM (2,99 GB usable) and 32-bit Windows 7. I even gave a dataset of 66 000 000 nodes but not even dreaming to work with it yet.

It seems like I need to buy something more powerful, so I want to hear your advice about that. What configuration of CPU/RAM is good enough to feel comfortable with such datasets?

Thanks in advance!

Best regards,
Alex.
