@ Jack, a friendly disagreement.
I really dougt you would see that 21% difference between the M4 an the "Tier 3" listed. Benchmarks yes, but not in real life operation. Ex If a program opens in 20 Millisec vs 30 millisec ( an increase of 50%). But would a user see the Difference - dougtfull.
And Yes I'll take the M4 and the Samsung 830 before the ones you listed.
