it may work. What's your use case?
If you are talking to me my case is that not all desktops and laptops have 64bit drivers some only have 32bit.
sorry, I was addressing the OP and wondering what he's planning to use the PC for.
I used to run Windows XP x64 in the mid 2000s so I've got a pretty good idea of how the support stands. It's not a pretty picture right now and many manufacturers have dropped support for it.
I was going to install Microsoft Office 2003 Professional and Mixcraft 6. I just want to be able to use more ram in a Windows XP environment.
I tried Windows XP 64Bit on a different PC and it worked but the only thing missing was the audio drivers. I saw that Dell has drivers but I wanted to make sure that they worked on Optiplex 760 USFF before investing more time.
There should be no issues running Windows 8 on that PC. Drivers for all the components should be available. If you're unsure, you can download the Windows 8.1 trial to find out.
Dell has only a few proprietary hardware components, and these are typically found in their servers. The rest are just dell-branded components from other manufacturers that use fairly standard drivers. I'm not aware of Dell having any Audio chips of their own, so it's most likely just some random Realtek/CMedia chip.
