It depends on your definition of new. If you mean unused maybe, in the term of a current board then no. Every Intel s1155 board supports UEFI. Basically most AMD AM3+ boards support UEFI, FM2 boards must likely all. Imho UEFI is the coolest thing that you can use, especially when you use direct boot without grub - that saves you at least 5 sec from boot time. Btw. every board that supports UEFI Secure Boot (those with Win8 Logo on the product page) has an option to disable Secure Boot - so no problem at all. Also the default is usually that the CSM which is used for legacy OS which boot from mbr is on. Whenever you use an old gfx card without UEFI GOP then the CSM will be active anyway. Only with a very new gfx card with GOP mode or onboard vga you can disable the CSM and save extra initialisation time (also required for secure boot, some let you use secure boot with CSM enabled but thats completely stupid as you can already boot vom old legacy boot media).
PS: All boards are basically banana ware that you buy, so look for firmware updates - in most cases they fix uefi problems. Update immediately - the most simple solution for that i saw in new Asrock boards which had an integrated firmware update with online check for new versions and update directly from that.
