Lenovo has a deal that appears to be week-long, up to $600 off some of their gaming-oriented Y500 series.
Haven't bit yet, but tempting.
CPU: i7 3630 (quad core, 2.4GHz turbo to 3.4)
GPU: NVIDIA GT650M - A fairly decent GPU for the price range
RAM: 8GB (16GB on the $1000 one)
Screen: 15.6" (1080p on all but the cheapest)
HDD: 1TB 5400RPM
ODD: DVD/CD drive (+BluRay on the $1000 one, doesn't specify read/write capability, so probably read-only).
(all below include all of the stuff that their predecessors include)
$799, all basic specs, 768P screen
$849, 1080P screen
$879, 16GB cacheing SSD included
$999, 16GB RAM, BluRay drive.
