You actually burn through quite a lot of magicka as a stam sorc with streak, boundless (that's right, thundering sucks) and crit surge. That extra magicka and regen will definitely be beneficial to you. Sure the damage won't necessarily be as high as an Imperial, Orc or Redguard, but magicka still helps, a lot.
Try it out until race changes arrive. If you don't like it, you can always change.
