The mobo manual "recommends" that you should use the latest supported OS to "maximize" your features. So this made me wonder a bit because my Vista "Windows Experience Index" is 5.9, which I don't think it was too much lower before with 3.5 year old hardware. Does Vista bottleneck performance with new hardware? Should I upgrade to Windows 7 or else I would suffer some sort of performance hit? I'm not using any SDD's or multitouch screens or anything like that.
