I really don't know enough about video cards to really get an idea as to what my Mac can and can't run. I'm sure I can't run brand new games...but there are some older games I'd like to run. Like Sim City 4 haha. OSX 10.5.7 2.66 Intel 2 Duo 4GB 800 MHz Can I run stuff like Sim City 4 or The Sims 2...or even 3 (probably not). Thanks for any help...I feel sort of embarrassed having to ask.
