gpt or mbr

My computer is an old phenom 2 quad with a bios and my largest drive is 1tb. Well actually one of my thumbs sold as 2 tb and reports 1.9. When I wipe the hard drive and install 15.3 should I use gpt or mbr?

I use gpt and pmbr boot…

It depends on what you’re used to, if you ever got used to working with partitions and booting in the first place. If you’re used to letting YaST do everything, just do whatever it recommends. If you’re comfortable with the old MBR way, keep using it. If you never really got used to working with Grub and partitioning directly, go with the new way. I only use GPT in conjunction with UEFI, thus only on machines new enough to have UEFI. On all older, which is tens of machines and hundreds of partitions, I’m still using Grub Legacy and MBR almost exclusively.
