1280745	2012-06-09 21:25:00	Go 64 bit. Most if not all computers you buy these days are 64 bit. 32 bit is restricted to about 3gb of ram where as you can run something like 32gb of ram with 64 bit. Everything is also faster with 64 bit. :)	Trev (427)
1280746	2012-06-09 21:52:00	Thanks. Now the next question.	Vince (406)
1280747	2012-06-09 22:07:00	Depends if you have any legacy software. At work all our PCs use Win 7 32 bit for that reason. Some we have to leave at XP because some software like NaVision will not run on Win 7 of any flavor. At home I use 64 bit as I don't have any old software that won't run ..	paulw (1826)

The raw limit for a 64-bit OS is 2^64 bytes of RAM, or 17,179,869,184GB. The actual limit depends on your OS: for Windows 7 Professional and Ultimate, this limit is 192GB, which is still more than enough. Everything is also faster with 64 bit. Not necessarily. Only applications which benefit from large amounts of RAM will see an increase in performance, but 32-bit and applications that use little RAM will see little performance difference. Depends if you have any legacy software. Of course you could use XP Mode or dual-boot, and get the best of both OSs.	pcuser42 (130)
1280750	2012-06-10 05:04:00	For legacy software, win7 pro lets you run xp mode.	Nick G (16709)
1280751	2012-06-10 05:33:00	That is good to know.	Vince (406)

To my knowledge 64 bit CPUs have a 64bit data bus but usually only a 36 bit address bus - so 2^36 = 68,719,476,736Bytes. (68,719,476,736/ 1,073,741,824= 64GB).	johnd (85)
