[G4] Will a newer video card help?

[John Erdman]

OK You've convinced me that a more up-to-date video card will probably 
solve my problem. I wasn't nearly as sure before.  And I do like the 
idea of being able to support two monitors. Thanks for all those 
responses.

I was leaning toward the ATI 8500 when I wrote because I'd found some 
for a semi-reasonable price on eBay. I'd looked at the nVidia geForce4 
Titanium, but decided that it was too pricey to put in my old war horse 
now. But I hadn't considered an older version of the nVidia product. 
How does that nVidia ge3 card compare performance wise with the ATI 
8500?

I assume that there are Mac and PC versions of these cards and that 
they are not interchangeable. Is that right?

Also no one answered my question about how can I tell (ie. measure) 
whether my Medal of Honor game's performance is being limited by the 
CPU vs the video card. Is there some sort of a bench mark I could use 
to determine this?

Thanks,
John
