Will a 32bit OS bottle neck a quad core cpu?

They are full of crap. Really, the only benifit of a 64 bit os is being able to address more memory. Andrew0987

but did you hear some game site reported they got a 20% increase in preformance IN USING A 64 BIT OS over a 32 bit.

Someone is claiming that running XP or Vista 32bit will cause a quad core to run slow. True or untrue?Infinite-Zr0

I've never heard anyone say that before, anyway it's a load of **** my QX6850 runs amazing on 32bit XP Pro.
