Mine came with 2 DVDs - one for 32 bit and one for 64 bit. SO you don't have to choose until you actually install.

On my laptop, the 64 bit is great, and faster than vista was. I did a clean install.

On my desktop, the 64 bit installed onto a new hard disk, I had a problem (see earlier post) with my Nvidia 8400GS, but the driver problem is not related to W7 but to Nvidia. For every driver after 162.50 up to and including 191.07 I have no second screen in XP either.

The general opinion seems to be go for 64 bit if your PC can do it, and your peripherals are recent. I dithered for a long time and read a lot of web opinions. With 32 bit, you can never use more than 3328MB of installed memory - that is what my WXP reports despite having 6GB.
