lenovo y560 i7 and i5

so im kind of set on the lenovo y560, still searching for other laptops, but im really drawn to the y460 and y560. and if pricing was cheaper on the y460 id def go for the y460 but with all the sites and coupons i see both are about same price.

right now i see the i7, i heard that theres no switchable graphics on that but there is on the i5. Is it worth it to just get the i5 for the switchable graphics, and downgrade in the processor speed. i mean how much faster is the i7 to the i5? i dont do a lot of vid editing but i do a lot of gaming/ alt tabbing out and browsing and what not, while gaming so i think im sure i only need i5, instead of the beast i7.

 

is the i7 dual core or quad core?

 

its the quad core,

 

Do you need the extra battery life? With the ATI you will see ~3 hours and with the switchable ~4 1/2 hours.(Web surfing, word) Most games are GPU dependent, so the i5 would be just fine.
