32bit or 64bit windows 7?

Hi

A very debatable question, IMHO its 64bit if the game supports it, but as most dont then still if its a game that will run on 64bit Windows 7 then go for 64bit Windows 7, I'm running 64bit Win7 Ultimate and current games like CoD MW2 run great.

But also depends on your hardware, do they all have 64bit drivers? if you have to hunt and fudge drivers to work then go with 32bit Windows 7 but again if drivers are available, running Vista drivers while many work, they will only be a workaound and not native Win7 drivers so not the best fit.
