Windows 7: Should i swap to x64 version

Hello,

I have a Lenovo N200, core 2 duo 2.1GHz T8100 and 3Gb of ram. I just reaplise (i know a bit late ) that my processor is x64 and i am thinking about swapping from Seven Pro x32 to x64.

Do you think it is worth? Will i see/feel the raise of performance?

thank you,
Peter

This could go both ways for you, you might see nothing if you upgrade to x64. But if you are planing to install more memory then you should go to x64bit. Other then that I dont see much of a change in the two unless you have memory hungry apps IE Photoshop.

• How do 64-bit instructions help with security?
64-bit-capable processors have the ability to run the 64-bit versions of Microsoft's substantially more secure XP, Windows 2003, and Vista operating systems. Those operating systems are more secure because Microsoft, having learned many lessons from mistakes in the past, made the firm decision to lock-down their 64-bit OS kernels. The 64-bit Windows kernels actively police themselves to guard against many rootkit-style and other kernel attacks that have caused so many problems for users of the 32-bit Windows operating systems.

These advanced kernel-protection technologies cannot be ported back into current or even future versions of Microsoft's 32-bit operating systems because doing so would “break” so many existing programs and drivers as to make the system impossible to use. Microsoft knows that one day the personal computing industry will have moved over to 64-bit operating systems much as we all once moved from the 16-bit based systems to 32-bits.

SecurAble indicates by displaying either a “32” or a “64” whether the system's processor has the 64-bit instructions or extensions necessary to run 64-bit versions of Microsoft's present and future operating systems.

I changed from 32bit to 64bit last night and i didnt find any differnce in the performance at all really infact it seems a little slower to me but if you only have 3GB of ram and are not planning on going any higher you may as well stick with 32bit.
