It will be interesting to see what 8.1 looks like.
You're probably better off upgrading your PCs to Windows 7. If you have at least 5 that need to be upgraded, then I believe you can qualify for volume licensing which should be significantly cheaper than buying Windows individually.
In any case, you may want to do some testing sooner than later. I don't believe Windows 7 Enterprise evaluation is available anymore, but you can download a free
90-day evaluation of Windows 8 Enterprise. Note that this version cannot be licensed or upgraded to full version. It's just for testing purposes, but will give you an accurate idea of how well it will work for your purposes.
