Well, Since 2005(I guess) Windows has been launching 32 bit and 64 bit versions of their OS’. They are bit different or may be you can also say they work differently. They were implemented to increase the capability of handling max Random Access Memory (RAM).
Choosing between Windows 64 bit and 32 bit is really a big decision, but you must be careful while choosing one. These days all the newly bought computer systems are delivered with 64 bit OS, you know why? Answer is simple the 32 BIT operating systems were designed to support maximum of 4 GB RAM, where as 64 Bit OS will support 4GB and above.
So what should you choose?
The answer is. If you are having 4GB or more RAM, then to juice out every single drop out of it, you must install the 64 bit. 64 bit will let your hardware run at its max. If you are having less than 4 GB, you may give it a try.”
What will I be risking installing 64 bit?
As you know before 64 bit came out 32 bit was everywhere and people till today use those in high number, so the availability of software support for 64 bit is less than 32 bit, However many software run on both 32 bit and 64 bit without problems but some software don’t. So, you may have trouble finding the software compatible to your OS.
Not only that, the another problem is driver support, certain drivers may not support your 64 bit so the device may stop working, you will need to search perfect driver compatible to your OS.
What will I be Losing if I don’t use 64 Bit?
Well, you know the ability of handling maximum ram is better in 64 bit version, so the operating would be better and smooth. you will be losing this control.
These days many software are built to better use capability of 64 bit machines, so this would be great.
Beware, 64 bit operating system use more RAM than usual, The operating system will take one or couple of GB more than usual to store its operating system and software.
I am just a Gamer, will it matter for me ?
I have seen that many games run smoothly on both 64bit and 32 bit without any difference but I still think 64 bit is deserved by 4 GB + machines.
