Hi all. Hopefully someone can point me in the right direction. I have an 8-core 3.2GHz 2008 Mac Pro with 16GB RAM. I've just ordered the EVGA NVIDIA GeForce GTX 285 graphics card and am hoping to turn my beloved mac into a bit of a sexy PC gaming beast for some evening fun. Already purchased Batman Arkham Asylum, Gears of War and an Xbox 360 controller to get me started I'll cut to the chase. Microsoft are offering a free upgrade to Windows 7 if you buy Vista at the moment so that's not the issue. The issue is 32bit or 64bit for a gaming box - which is the best version to get for performance and compatibility with gaming on windows? I'm looking to purchase either the 32bit or 64bit version of Vista (with the free upgrade to the corresponding Windows 7 version). Which is the best to get? 32bit or 64bit? I've been reading that some games don't work well with 64bit Windows. Lots of conflicting articles and comments. 32bit or 64bit Windows... what's the best for a bootcamp gaming rig? Thanks!
