Gateway NV75S17u vs. ASUS K-series?

Hello,
So I'm looking for a new laptop (not totally for gaming, mostly for multitasking/more intensive Internet use, etc etc) and right now my two options are listed below. Recs? All thoughts appreciated!

1-- Gateway NV75S17u
CPU-- AMD A8--3500M (quad-core @1.50GHz, 4 MB L3).
RAM-- 6 GB DDR3
Videocard-- Haven't searched/found much, but I know it's a 512 MB dedicated.
Price=$600

2-- ASUS K-series
CPU-- Core i7 2670QM (quad @2.2GHz, 6 MB L3).
RAM-- 6 GB DDR3
Video-- Integrated Intel® GMA HD
Price=$800.

I'd really like to keep the price under ~$700 but I could probably scrounge for the ASUS if it's really worth it. If you guys had any other recs, I'd certainly love to hear them! Thanks!
