Should I return my HP for another cheaper 17inch HP?

I bought for $430 a 15inch HP AMD A8 , 650GB HDD laptop.

I noticed that there is another HP available for about $350, Intel950 processor, 17inch. 500 HDD: http://www.bestbuy.com/site/HP+-+Pa...10958394&skuId=6892279&st=hp 17inch&cp=1&lp=1

I like 17 inch and I think Intel 950 is probably fast enough. What do you think?
Does A8 make internet browsing faster?

And then I found something for $500 that seems to be much better: http://www.bestbuy.com/site/HP+-+EN...08243926&skuId=6819278&st=hp 17inch&cp=1&lp=2
Regular price is $700, it is $200 less than that now.

But the $500 one is not available in stores. I got my current HP from having my Toshiba junked out. Do you think I can get the one online while returning the one I got?

 

What you've got sounds better than that more expensive or cheaper notebook. For the price that sounds really good, would be a well balanced system.

Of those three I'd pick the A8 one you've got over the other two regardless of price. I mean I'd pay more for it than the inexplicably more expensive one.

 

How is the one I have better than the other two?

 

The more expensive one went back up to its normal price.

But I found another good deal. For $400 there is an A8 17inch http://www.bestbuy.com/site/HP+-+Pa...lack/7015368.p?id=1218821793451&skuId=7015368

It's 30 dollars cheaper than mine, has bigger screen, but slightly less HDD.
