I balked on a refurb Z480 (14") on the Lenovo Outlet last night for this same price. But I think it had the i3-3110, which has a 3046 PassMark score.
I also was lucky enough to get my hand on one of the Lenovo Outlet for i7-3520M @ 2.90GHz laptop (scratch & dent) few days ago for $446 + tax. I was afraid that it might get cancel, but I got the shipping confirmation yesterday. The inventory comes and goes. With these Lenovo outlet deals, you just have to keep on refreshing it the day of. I have try many, many times before seeing one being available.
Prior to this, I also brought an scratch & dent i5 U400 for $400. As for the scratch & dent, I cannot see any at all, looks brand new to me. Just hope I have the same luck with this new i7 laptop.
