Vista: 32 bit or 64 bit?

[Joeygates]

Hi,

I'm looking into purchasing Vista for my new PC. Is it worth going to 64 bit? Or are there too many problems with drivers right now? Im getting one of the 2 processors:


Intel Core 2 Duo E6400 Conroe 2.13GHz LGA 775 Processor Model BX80557E6400 - Retail

or


Intel Core 2 Duo E6600 Conroe 2.4GHz LGA 775 Processor Model BX80557E6600 - Retail

If I stick with 32 bit, will I be severely bottlenecked?

My other question is if it is just work going with XP home right now and upgrading to Vista later. I'm hearing a lot of problems with Vista.
