    Could someone tell me if allocating RAM to Windows in Boot Camp affects the amount of RAM available to Mac OS X? I need all the RAM I have for graphics intensive apps.

    no... the two os do not run at the same time... when you are in boot camp windows is using all your system resources it can and when you're in mac os x it is using all system resources... now if you are running your boot camp partition virtually via vmware fusion or parallels then the two os run at the same time and are sharing your ram in your desired allocation... i run vmware fusion and have 1 gb of ram assigned to windows xp pro and 3 gb assigned to mac os x and both run perfect... a lot of people use xp virtually with 512 mb of ram and have no issues

    They're not connected. When you load Windows you have a Windows PC - OS X is just sitting there on the other partition, dormant.

    So you'll have your full quota of RAM in whatever operating system you're in.
