mchn i have 4 gb ram 512 ATI vga laptop.currently im using Win XP.i would like 2 upgrade to win 7 ultimate.please let me know which one i have to install is it 64bit version or 32 bit?
U should go for 64 bit if u want to use ur whole 4GB RAM & get the advantage from 64bit apps. (I assume that u have a 64bit capable processor) 32bit supports max 3.25GB RAM.
