Most of it depends on how large of a sump you are going to use. You wouldn't want 1200+ gph flowing through a 20 gal sump. Personally I think 800-1200 GPH is more then enough if considering a 30+ gal sump. Having said that I'd still buy an overflow that is rated higher like the CPR CS102 which handles up to 1400 GPH.
