Wait for it. The 870m is a really hot GPU. The 970m is cooler and these have been proven by the various video reviews of MSI GS60's side-by-side comparison of the same laptop but with 970m and 870m on each side. I'm pretty sure it will be the same for P35. If you don't need the video performance, go for the P35W v3 with 970m. Don't go for the P35X with 980m as it usually 300 dollars more expensive in the various sites that have them in pre-order listing. The 970m has surpassed last generation's flagship 880m in terms of performance so it should be plenty strong enough.
