I'm on a iMac 400 G3, and I have noticed that my gaming performance has decreased incredibly. I know I can't really get that much out of it anyway but when I first got it performance was way better. So if anyone out there knows a way that i can beef up performance without hardware upgrading, I would be thankful.
P.S. I have already upgraded the only thing I can RAM, I'm on 512 so I'm good there!
