Just as a datapoint:I've used Vista64 with RAM totals ranging from 2GB, 3GB, 4GB, and 8GB.4GB will do you just fine for any game you might run. 3, actually, does fine. When I downgraded to 2GB, I definitely noticed a difference, but the change from 4GB->8GB has been about nil.I run games from about 3 years back until now, and have never had a problem running on Vista x64, and Steam works fine as well. I can't say for MS Office, but OpenOffice doesn't have a problem. If MS Office has a problem with x64 when their open source 'competitor' does not, they need to get to work cleaning the egg from their face
Aye, about the same for me. I am currently running Vista Ultimate 64bit, and intend on staying with 4GB of ram for a bit.
All of my games (Including sins) run fine on vista 64. And as others have said, I don't use MS office, I use OpenOffice, which runs fine too.
