I run the Windows version of NWN on my iMac 2.66 GHz 20" with 2GB of RAM.
I didn't even need to install it - just copied the folder structure from my Windows box with a USB stick. Then I open the NWN folder in Finder, double click the nwmain.exe (or nwn.exe for the DM Client) and it loads up in Crossover Games - full screen and much better resolution than my PC.
The only issues I had were:
1. The menu bar is visible at the top of the screen - no real problem.
2. The Dock was visible at the bottom of the screen and got in the way of the quickslots - I moved the Dock to the left and made it auto-hide, which looks better anyway.
3. The Toolset does not run in Crossover - it runs fine in Parallels, from the same folder that I use with Crossover.
The only minor issue is that batchfiles do not run in Crossover - so I can't setup those as I have in Windows. It just means I have to remember the passwords for online connections.
Neverwinter Nights 2 might be a complete failure (not tried Boot Camp yet), but the original Neverwinter Nights is great. A lot faster than on my PC, larger screen, better resolution. Works with the DM Client online as well.
