in the top sellers box there are 3. the ultimate is a bit ott for me really. the only real difference i can see between the home and the proffesional is that the professional lets you switch between windows 7 and xp mode so you can still use xp programes if you wanted to. is that about it? the 'home' version is supplied with the 32 and 64 bit versions but the pro version only comes with the 64 bit. whats retail and OEM difference?
The differences can seem a bit daunting but let me try and boil it down for you:
- With windows 7 the drivers for 32bit and 64bit are very good, so you won't have any trouble with new hardware when running 64 bit (this wasn't always the case)
- 32Bit can only address up to 4GB of RAM, that includes all RAM in the system (eg system RAM, Video RAM etc). As you are planning to use at least 4GB system RAM + Graphics RAM, then you need to run 64bit to make use of it all.
- From what I have read there is little/no difference in performance between 64bit and 32bit windows in applications and games.
As for which version- home premium, professional or ultimate, I suggest sticking with Home Premium. XP mode is only really useful if you have something that doesn't work in win 7 and needs XP to run.
Retail vs OEM. Usually OEM is cheaper, you only get the disk and a manual. Also, the license means that legally it is tied to the machine it is first installed on, also with OEM you need to pick whether you want the 32bit or 64 bit version as you only get one disk. Retail however, is usually more expensive. It comes with both 64bit and 32bit disks and arrives in a nice box. Also, it can be transferred from one computer to another. At the moment, Win 7 Home Prem. Retail costs the same as the OEM version - I suggest you get it now while it is at this price.
