Oh, I wasn't sure that the better GPU would be so much better then then 360m that the I7 processor and DDR3 ram wouldn't give the G51 a better benchmark for games or something since the G72's cpu got like 40th place for laptops while the i7 was in like 8th.
Newegg had that same ASUS g72 for $750 just a week or two ago, looks like they're sold out now tho.
For $1200, you can get something better than all of those. check out the Asus g73 at best buy... has the i7, gb DDR3, and ATI 5870, which trumps both those video cards. It's a great deal... the only downfall of it is doesn't have a 1080p screen or bluetooth. If you want the HD screen and bluetooth, check out the normal Asus g73 - but it costs $1500
