The Y580 is no longer on the Lenovo website. The Y500 with the GT750 with the option to buy a 2nd GPU for SLI is the better deal and still under the $1000.
And it will be faster then the GTX660. With SLI it is faster than the GTX675.
They are on sale for $470 off on the Lenovo site.
Sounds good to me.
Thanks for the info.
