Win 7 Ultimate x64 Bit ! - Doe's someone use it ?

[Hellion]

I am just about install it

Now im using the x86 (32 Bit) Win 7 Ultimate . What are the diffrents between them ? I know that the 64 Bit is using 4GB of memory , but that's it ?

64bit isn't using 4gig of ur mem, its using like 1 gig maybe and the diff between em is that with 32bit u can only use 4gig n with 64bit u can use as much as u want
