With current compilers little if any as long as you don't throw. You
should be able to get slightly better performance with
try { doSomething(); } catch(..) { handleError(); }
style code than with
if ( !doSomething(); ) handleError();

s/might/should/
Everyone else does it the way they do for good reasons!
