Two laptops performance in games.

About to buy a new laptop for general gaming because I'm on the go a lot. Currently using one of the gateway fx series laptops from about 2 years ago.

I am deciding between these 2.

ASUS G73JH-BST7 about ($1299)

Intel Core i7-740QM 1.73GHz Processor
17.3-inch 1600x900 LED Backlit Display
6GB of DDR3 Memory

640GB 5400RPM Hard Drive
DVD+/-RW/CD-RW drive
8-in-1 Media Card Reader
Four USB 2.0 Ports, One HDMI Output
10/100/1000 Mbps Fast Ethernet LAN RJ-45
Embedded 4G WiMAX Mobile Broadband

ASUS G73JW-XT1 about ($1499)

NVIDIA GeForce GTX 460M graphics with 1.5GB DDR5 VRAM for unprecedented DirectX 11 gaming

Everything about the second one is better obviously except I heard the 5870ms were faster then the gtx 460m. It's going to be for gaming so I'm having a hard time finding the exact benches of the 2 to see how far off they are. Obviously the second one has a faster HD, the video card has a bit more ram, and the system has a bit more ram. If there is a significant speed difference just because the 5870m is faster then I would go with that, but I am having a hard time finding a side by side comparison.
