I'm looking to buy a new gaming laptop soon, and I've narrowed it down to these two: the Lenovo Y580 and the Sager NP9130.
Lenovo has i7, 660M, 500GB HDD, 8GB RAM, 1920x1080 screen for $1000.
Sager has i7, 670M, 750GB HDD, 8GB RAM, slightly better 1920x1080 screen, better wireless card for $1100 (Or I can get it with an i5 for ~$1040)
Important things are performance and general build quality (also battery life to an extent)
I'm kind of leaning toward the Sager, but I don't know if I really want the 670M since it's built on Fermi, not the newer Kepler.
This is it, though. Any advice is very much appreciated; I've been trying to decide forever and I just don't know what to do!
In your case, I'd say the Y580 - better battery life + the fact that the screen on the Sager isn't the best. The upgrade option will cost to much.
The difference in the performance is not something that should bother you as it won't do any difference almost in no case.
Another thing is that with the money that you save you can buy a nice mSSD or SSD for your Y580.
I'd take the Y580
I can get the Sager with an i7 for $1100. I don't know if that changes anything, but I can. Also, would I be able to overclock the 660M in the Lenovo?
Apparently the 660m runs cool enough to allow it to be overclocked quite well.
They say you shouldn't overclock laptops, but with my Y570, (i5-2410m+GT555m) The GPU also ran extremely cool, Overclocked it by +300Mhz and the card still sticks at 75C MAX playing games like BF3.
The GT660m would seem to be very similar, i've seen a few forum threads applauding their 660m overclocks to +350Mhz, bringing it past the GT670m in performance whilst still remaining cooler then the 670m during gaming.
By the looks of it, the Y580 has the same JBL speakers as my Y570. These speakers are absolutely fantastic quality.
*I have ZERO experience with sager products, so hopefully someone can come in who does have some, and provide a counterargument as to why the other should be chosen.
