I'm looking @ Core 7. and was wondering if I needed to i386 or the x64

as I wish to use Hyper-Threading from my P4 3.6GHZ

You can use either (assuming your cpu is 64bit). Most would recommend that you stick to the 32bit(386 iso). Unless you are doing industrial strength computing or have more than 4gb of memory you will see only minimal performance difference. Most of the howtos and help will be 32bit based. There are also a number of things that are more difficult to do in 64bit(flash, sun java, etc). Until you really understand what you are doing I would stick with 32bit.

Good Luck

ah I'm just looking @ a webserver... ran great on windows using a 32-bit os. was just wondering if the kernel will use that HT like windows did

Yep, Fedora has been smp at least since FC4(three years ago?). Just be aware that the software (regardless of OS) has to be multithread aware in order to make use of it(within one application).

a p4ht 3.6 is very unlikely to be 64-bit. my p4ht 3.0 is 32-bit.
