Why?
Mother Board should have 64Bit Support ne?
It's not the motherboard. It's the CPU that has to have 64bit.
For example, there are S775 Prescott CPUs which are 64bit and not. Both can be installed on the same motherboard provided the motherboard supports the new CPU. This support has nothing to do with the 64bit. Just that the motherboard has to identify this new processor - that's all.
64bit is all in the CPU. Having just a 64bit CPU doesn't mean anything either. You need to have a 64bit OS, otherwise it will still work in 32bit mode. Having a 64bit CPU and a 64bit OS doesn't meaning anything either. You need NATIVE 64bit software to get the advantage.
Yes, you can run 32bit software on a 64bit environment as long as they are compatible. Most system software doesn't work without modification because they have to work with the system. Still, only 64bit native software will benefit from 64bit technology, not the compatible ones.
But in Vista, there are restrictions for normal people to move to 64bit.
* All your drivers have to be not only 64bit, but also digitally signed.
* People who overclock their video cards are lost, unless they mod the BIOS (which I will do as soon as I get the BIOS

)
* You need to have more RAM, because native 64bit software allocates larger chunks of RAM than before, whether or not they are used. 64bit on a 1GB RAM PC doesn't make any sense. Even 2GB is not quite enough actually. However, if you have 4GB, you don't really have a choice because you will have to use 64bit for the OS to
see all your RAM.
* Software support, even from the well known developers sux!!! At least Microsoft should have made a 64bit Office suite. Adobe doesn't have a 64bit flashplayer, so we can't use a 64bit browser.
