Windows vs Mac laptop

Hi fellow kirupaians!

I’m looking to get a new notebook as my current one has unfortunately crapped out on me this week. :doh:

I’m more of a Windows woman, but I’m highly considering a Mac this time around. However, I’m not new to Macs by any means. In fact, I’m typing this from a Mac mini right now.

I’m a graphic and web designer, so I constantly have hi-end graphics apps running at once (specifically- Photoshop, Illustrator, InDesign, Flash).

I’ve done a bit of research and this is the PC I would be getting - http://www.toshibadirect.com/td/b2c/pdet.to?seg=HHO&poid=419828 (Toshiba Qosmio G55-Q801)

Are there any mac notebooks that can compare to this? I’m looking for speed/high performance/multimedia.

Thanks for your time. :toad:
