Which processor would be better for games and office work?
the pentium 4 3.6GHZ hyper threading 533MHz fsb or the AMD 64 2GHz HT 1600MHz FSB? the processor that i decide on will probaly be combined with a Radeon 9800, 9800 pro or 9800XT
I think you mean 3.06 ghz, not 3.6 ghz. The fastest processor Intel currently makes is 3.2 ghz. Of course, the Intel Pentium 4 processor is a 32-bit processor just like just every processor up until now.
Apple just released the first 64-bit personal computer a few months ago - the Mac G5 64-bit processor manufactured by IBM.
AMD is following in suit with the AMD64 processor.
Apple released a special version of their Mac OS X operating system to be compatible with the G5 processor. If you're a Windows user, you will need to use WindowsXP 64-bit edition if you want to use a 64-bit processor such as AMD64. Just look at the speed of that frontside bus (FSB) the AMD64 can boast (compared to that of the 32-bit Intel processor).
Of course, a 64-bit operating system can take some advantage of a 64-bit processor. However, it's still going to be a few years before a lot of software has been released that's been programmed to take advantage as well. Once the software is out, you'll see an enormous performance gain over 32-bit processors.
