Should I get sager np8235 or lenovo y510p

[Realbrizzi]

I want a laptop that will last me a long time with great performance, I think I have it between these two.

Sager np8235:
15.6 108.
Gtx 770m
I7 4700mq
8gb
Win 7
750 gb 7200
1419.91 tax and shipping

Y510p:
15.6 1080
Gt 755 sli
I7 4700mq
16gb
Win8.1
1tb 5400 + 24gb ssd
1308.45 tax and shipping included

Couple questions:

1) which one will perform better graphically?
2) which system will have better cooling and lower temps?
3) which one has better build quality and longitivtiy?

I would like to get 5 years if I could even tho that is probably pushing it. Cheaper is better but if the sager is worth the 100$ ill do it but spec wise it's short so that's why I was wondering about the build quality and longitivtiy. Thanks for the answers.

Ok,first answer: The Gtx 770m is 20% better than the Gt 755 sli (Sager np8235 is better with its graphics).

Second answer: I think that Sager np8235 will have better cooling but if you overclock heavily it could get hot,and you dont need a cooling system for it because it has EVGA ACX cooling which is a very good air cooling system anyway.

Third answer: Again i would go with the Sager np8235.

Hope it helps you .
