Hi, I'm going to get an iMac 3.06 GHz with 4 GB of RAM and a nVidia GeForce 8800GS! Mac OS X will be used for everything except gaming. 1. Which Windows version is better suited for gaming (Crysis, Half-Life 2), Windows XP (SP3) or Vista (SP1)? 2. Are there drivers for the graphics card? If not, is gaming even possible??? 3. Would you recommend a 32- or 64-bit OS? 4. How big should the BootCamp partition for Windows be (with space for ~5 game installs), is 250 GB enough? 5. Do you have any other recommendations? UPDATE: I'm going to install Vista! However, I still don't know if I should get the 32 or 64 bit version! Thank you.
