So I want to buy The Sims 2 for mac, but my computer's video card is the ONLY spec not met...?

I have a Mac OS X Tiger edition, and everything else about this machine exceeds the system specs for the game--except the video card. The game doesn't support the Intel GMA 950, and I'm confused as to what this means. Does this mean that the game won't play at all? Or does it mean that it will still play, but with a lower FPS? Be merciful in answering, I'm naught but a teen with a low understanding of technology.|||the game wont play on macs the video card is to weak ---macs has never been knwon as a game machine
