Asus N56VZ vs Dell Inspiron SE 7720

And I see 5 or more MODELS. As such, you would get 5 to more benchmarks to compare. I can't do that for you.

If you are fine with 2 year life spans then it's good to go.

However why are you comparing a 17 inch laptop to a 15 incher?
Bob

i go to be a Software engineering student and i need comfortable computer(17 inch), but I'm afraid dell's battery ..
also i want to play good games like COD so i need Powerful computer..
and my freind said the Asus is better but i love the dell more then the asus , but again ..I'm afraid dell's battery.
what you think i need to take ?
and which computer get 2 year life. and why ?
i need computer for all my Period of study , 4 years.

sorry but i dont have a good english !
and Thanks very much !

It's that simple. To get all that performance into that much space, the temperatures go up, the life span goes down. It's just like a high performance car. It doesn't last as long.

I am not saying this will only last 2 years. I'm saying you have to be OK with with that if it happens. Many gamers burn out their laptops in that much time.
Bob

i dont go to play so much .
mybe 12 hours in week , in the other time i go to write Software and use office..
it's ok ?
how much hours in week of gaming Hit the computer?

you offer to me to take i5 ?
and dell or ASus ?

thanks !

And while a gently user helps, it's still an high end sports machine and the life span does go less than your boring laptops.

The 17 inch units also suffer reduced life spans with students since they schlep the laptop around and your average Inspion is a bit "bendy."

The Asus is a good machine but it appears you can't accept the lower life spans of high performance laptops. Try this. Add a 4 year warranty and then it's not your problem.
Bob

ok ..
so wich Processor and Graphics Card i need to take for high life spans , and that run COD ?

I have to go with the laptop with the longest warranty. It appears you are new to PCs in general. That is, it's a recent development to get the high end GPUs inside a laptop. And if you have followed laptops for a few decades, not much has changed in regards to the high end CPU and GPU with it's higher heat output has always resulted in shorter (on average) life spans.

At least you know this now and will get a warranty to fit your needs.
Bob

Ok , Thank you very much !
