Best GPU for under £150

Hello all

I am looking for a GPU for under £150. I have found a EVGA GTX 650ti BOOST SuperClocked for £149.39 but I was wondering if that was good or if there was a GPU better or the same power for cheaper. because the GTX 650ti BOOST is new they are not on any GPU comparison sites so I cant look that way if anything is better

thankyou for any of your help
