Yes, surge protection is worth it. It will have no effect on performance.
Surge protection is like insurance. The more worried you are about a power surge and the more valuable your asset (computer) is, the more you want to spend on surge protection. I live in an area where we have lightning 3-5 days a month, so I have a whole house surge protector and small surge protectors on each computer.
Recommendation ... Look for a joule rating. The bigger the number, the more protection you get. Balance rating with price to find your best choice.
