64-bit Windows looks and feels exactly like 32-bit Windows. The only diferances are that 64-bit Windows is, well, 64-bit. It uses the WOW32 emulator, which alows just about all 32-bit programs to run just fine. However, anything that interfaces directly with the kernal (anti-virus, anti-spyware, drivers, etc) MUST be designed to run nativly in a 64-bit enviroment. So far, I have not found any driver problems, however.

<div style="font-style:italic">if a 64bit CPU runs 32bit windows it isnt fully utilized</div>
</div>Shouldn't that be fully clarified, AMD 64s fully support 32/64 bit processing. That was the tech Intel aquired from AMD.
im on it right now. . it makes 64 bit threaded programs run faster (i know far cry has a patch and i think photoshop and some others have x64 vers) there are some driver issues (like i cant run my M$ fingerprint reader) but not many. your new system shouldnt have any problems w/ drivers (asus is pretty good about x64) <br />
BTW you can get x64 pro OEM copies online for around 80 shipped. . .thats how i got mine. .. <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" /> its less than pro x32!
64BIT Windows is Identical as its 32BIT counterpart the only difference is that its Coded to use 64BIT addressing in 64BIT enabled CPU'S.<br><br>
64BIT adressing is alot faster as more DATA can be processed at any one time..Thus 64Bit can be alot faster in some cases.
