no problem with mine.
I run the entire Adobe Creative Suite + Quark 8 on a 2.4 AL iMac w/4 gigs ram and it handles it all without even breaking a sweat. And I'm talking multi hundred meg Photoshop files and 100+ page Quark files with gigs of links. Not some crappy little 72 dpi web graphics and a few 3 panel brochures.
Whats a "very good deal"?
