Well...a 460M isn't a stellar GPU. I'm not sure the exact GPU that's going to be on the PS4 and Xbone, but I think they'll have more power than a laptop.
+1 no mobile parts are going to keep up with the Xbox (roughly Radeon 7790) or the PS4 (roughly between 7850 & 7870 but with access to shared 8Gb DDR5 RAM).
