At this point I woldn't say that it matters - magic is still in the "support" field more than anything, with more work being done behind the scenes that will be released within the next couple of updates. Pick a race that you like the look and feel of the most, not because of the stats. And all stats and skills can be trained equally regardless of the character race you choose.
Still, you can look through the
Races and check the starting stats - those with the highest Intelligence and Will will have more MP for magic.
