ok read some material you suggested and im computer illiterate compared to most members
anyway went to agear website and went to the customizer. i think the 740qm is enough processor and the upgraded thermal compound is inexpensive enough but is the performance difference enough to justify the cost to upgrade from ddrr3-1066 to 1333 ? same question with respect to having primary hd be 160gb ssd versus sata 500gb 7200rpm disc ? memory adds $249 ssd is $449.
