Windows 7 32 bit versus 64 bit


Likes # 0

Hi everybody

I am looking for a bit of advice on the merits of Windows 7 32 bit versus 64 bit.

I have pre-ordered Windows 7 Pro through Amazon and as the disk is going to come with the choice of both 32 and 64 bit versions I was considering taking the plunge and installing the 64 bit version but I have some concerns which i am hoping you guys (and gals) can help me with.

First question is, if I take the plunge and install 64 bit and its a disaster can I change my mind and install the 32 bit version and activate it using the same key again. Or to put it another way can I use both 32 and 64 bit versions with the same key on my machine as many times as I want as long as only one version is activated at any one time?

Next question is as I am an avid gamer what could the downfalls be? Now I'm not bothered about it improving performance in games as I appreciate that just about all modern PC games are programmed in 32 bit and as of yet very few have been "enhanced" to take advantage of a 64 bit enviroment. All I want is for the games to run and be compatible. Will a 64 bit operating system cause huge games incompatibility? Any gamer out there running there games with no probs? Please list successes and games that won't run under Windows 7 64 bit if at all possible.

Lastly I have a resonably up to date system (Though not cutting edge lol) I have 4 gb memory an Intel Quad Core Processor 2.4ghz and a Sparkle Nvidia 9800 GTX+, Realtek High Def Audio (onboard) with two hard drives that total over 800 gb.

How readily available are device drivers and how good is Windows 7 64 with its built in and generic drivers?

I know thats a lot in one go but any advice so I can make an informed decision when the time comes would be most gratefully received.

Many thanks in advance


P.S. I am running the 32 bit Windows 7 RC evaluation copy and its awesome !! ;-)

You're right, and I stand corrected. I was trying to make the point that you can only choose one version - you can't activate a 32bit version and then decide to activate the 64 bit version on the same licence, or vice versa.

My apologies for any confusion caused.

Hi F.E
Thats quite alright and i hope you enjoy whats left of the weekend ( Rain here in Cornwall)!!
I do think however that the whole issue of activation could of been better explained by the powers that be and i am betting there are still a few questions to be answered on the subject.We shall of course see in 11 days or so.

I have some XP programs that work fine. If get 64bit Win7 will those programs still work?

I tried 64bit Linux a while back and some programs woudl nto work as they did not have 64bit versions, whatever that means, e.g. some plug ins for Firefox.
