gaming laptop for 689$ help!

I'm trying to find a nice little laptop for that price that'll be able to play at least dirt 2 fine, being able to play metro 2033 and crysis and what not would be nice though. 15.6" screen is the biggest size screen I'd go.
I've been looking at these: NCIX.com - Buy MSI CX640-013US Intel Core i3 2310M 4GB 500GB DVD 15.6IN NVIDIA GT 520M 1GB USB3 W7HP Notebook - Others - 9S7-16Y111-013 - in Canada

NCIX.com - Buy Acer Aspire AS5552G-7464 AMD Phenom II X4 N970 6GB 500GB 15.6IN Radeon 6650 DVDRW WIN7 HP Notebook - Others - LX.RC402.067 - in Canada
The msi's got a sandy bridge cpu but a weak gpu, the acer has a weak cpu but a decent gpu (I think).

HP is garbage, MSI isn't great but HP just blows. For that reason alone I would go with the MSI SB lappy.
