Im torn between the two

The two links are the same

ok fixed it

i would go with the larger Acer Aspire V3 model. It has a much faster cpu, better graphics, and a higher resolution display that will certainly be noticable. And it's cheaper. You have to weigh whether the size is a big enough problem to make the smaller one worth the worse performance/resolution.
Also the V3 has a quad core processor while the timeline is a dual core so really the V3 wins by far except for in size.

The ultra book really sucks for gaming. the gt640m isn't that great of a card to begin with.

i wont have the money til the end of october just hope its sstill in stock. and also i was thinking of gettings the windows 8 version....but i tried the preview and just seems like unnecessary stuff. Any thoughts people?

from what i've seen i'm not impressed with windows 8. But some people do like the UI.

For gaming? You'd be fine with an i5, as 95% of games don't use more than 2 cores.

Get this when it comes out in a week, if you don't want a 17" laptop to lug around, but still want power equal to a 640m:

The 7730m and the 640m are about as good as you can get for the price you're talking about. You could also do the A10/7670m hybrid thing....but there's a catch to that: it can be as fast as the 650m but some games don't support CrossfireX so your performance would just be pure crap on those titles:
