I play alot of call of duty 2 on my macbookpro. 2.33 w/2gigs/256 Ati x1600. If I upgrade to the 3 gigs of ram, will I see significant performance increase in my gaming? Just checking to see if it is worth the price to upgrade. Thanks, Also, looking for suggestions for other games. COD2, Imperial Glory was fun, What else is really fun with great graphics for my mac-ee poo.
