Ok I've had a search of the forums and come up with very little.

My old PC is kaput!

I've read some posts that say Windows 7 64bit 8GB Ram is needed. I told the guy who is going to build me the PC and just received a razed eyebrow. 

Poser 7 Minimum specifications: 700MHz Pentium processor; Windows 2000/XP; 520MB RAM, 1GB hard disk space; Open GL-enabled graphics card or chipset recommended 

Now thats minimum. Whats comfortable - kick arse?

I'd rather spend a bit more to get something thats going to last me afew years.

Please help, I'm really crap when it comes to these things!
