Windows 32 cause lots of softwares and drivers dont work for Windows 64.
The good thing with Windows 64 is that playing 3d games, i heard that it gives more than 20% performance boost!
Yay, got my free host i guess =)
I think ill start posting some more later XD
a 64 bit processor will eventually give you a performance boost, just not so much right now, the Intel 486 to pentium was 16 bit to 32 bit, and it, eventually, allowed upgrading to win 98 se (before it died).
a 64 bit processor is not always give high performance. This highly depend on the compiler and the OS design. Some easy compiler support 64bit processor dosn't fully use the highly 32bit at all.
64-bit processors aren't generaly (in everyday use) faster than 32-bit processors. 64 bits basicaly means that the processoer can handle larger number 2^64. This advantage is best experienced in some mathematical calculations dealing with very large numbers.
64-bit programs are generaly 10-30% faster; but that time when the most of the programs are written in 64-bit technology is still to come.
I advise you not to install Windows 64-bit version as it is very very bugy (in my experience) and although you can use 32-bit programs just like before you'll still need 64-bit drivers, 64-bit antivirus and firewall software.
the biggest difference that i have found in my reserch of the topic is that 32-bit chips can only handle 4 GB of ram and 64-bit chips can handle 16 GB of ram. i'm not positive about the amount of ram for the 64-bit chip.
either way that doesnt make a huge differance since the majoraty of consumer motherboards can only hold 4 GB of ram (the max for 32-bit chips). so i would stay with win 32 untill vista because it was writen naitievly in 64-bit.
Windows x64 is faster for sure... and like every one said avobe that much more RAM and virtual ram can be added...
in some cons... one would say AVS is hard to come by... drivers r still a issue...
otherways when Microsoft is giving it free to try... yeah lets shift to x64 ... why not??
