[Inkscape-user] Minimum Hardware requirements to make inkscape useful.

Here's my system.

Windows XP Celeron 2.40 GHz 640 MB of RAM

I'm running inkscape and it seems to render smoothly until I get in the neighborhood of 300 nodes. Then things start grinding to a halt. I'm looking at upgrading my system which is now 5 years old.

Any suggestions on what configuration I would need to make using inkscape enjoyable? It would be really great if I could handle 1000+ nodes without too much hassle.

Any tips to increase render speed, ie working in outline mode, locking layers, using clones, keeping groups of nodes small, etc.

Thanks!
