lol never fall for sm3.0 and 4.0 crap ! First generation cards will always be slower to allow playing of games with all eye candy on for a certain technology e.g. hdr/sm3.0 and hdr. sm 3.0 was introduced with nv 6/x8xx(hdr) series and is however still not implemented in enough games and we have sm4.0 coming soon. Imo sm4.0 games will take some time to come out. Crysis might use sm4.0 but the implementation might be half baked and through a patch (same as farcry which implemented sm 3.0 in 1.3 patch). Future proof is a non-existant term when it comes to Gpus
