I'll get straight to the point.
CPU : Intel DualCore E6700 3.2Ghz
MB : MSI G41M-P23
RAM : Corsair 4GB, DDR3, 1333MHz
GFX : MSI nVidia 9800 GT MD1G, 1GB.
I am running windows XP since like...forever...loved it, hacked it, crashed it,cleaned it , used it again and so on...
I want to make the transition to Windows 7.. yes...i know it' s a bit to late...
Could some of you give some advice regarding whether it should be 32 or 64 bit version?
Get 64x Windows 7 Home Premium OEM.
The base level Win7 has potential to be unlocked to Ultimate, if you decide to do so in the future.
Windows 7 Home Premium is Ultimate edition with locked features. As you upgrade to ultimate, Windows just unlocks features. It is great for a basic user as it allows you to upgrade versions without having to worry about losing your files.
