CPU is fine aswell.
Useful to say what components you end up getting.
New mobo = (highly recommended) format & reinstall OS. Can backup current HD/partition as is with your docs, etc then recover just the latter. Use this.
Could you go up to a 790i? Would be more future proof![]()
For backup, you don't really need an external HD just either use a spare HD or re-size & create a new partition (re-partition) on current one & back-up there
In this situation, 'backup' is so that he can (re)install OS since upgrading mobo.
