Aspire One question

I Just bought a Aspire One AO721-3574
Clicking the link gives the specs.. I also noticed ( Havn't opened the box yet.. Frys purchace ) that Amazon sells the dual-core version.

The AO721-3574 is 1.7 ghz processor
vs
Acer Aspire AS1551-4755 1.3 ghz

The Cache size is different.. the single vs dual core..

I want a netbook that is new, good for cards and netflix via hdmi to TV.. The graphics is ATI Radeon HD 4225 Graphics with 384 MB of dedicated system memory.

So I want it for Media Center.. Hulu ... Hooking up to the Sony Bravia TV... Playing cards and serving the web.. But I'm stuck on having some graphics : )

What do you think? Will the duel processer be better or worse.
I don't know if the 1.7 will be better or the dual 1.3.

Will the dual 1.3's dramatically effect battery life?

Then of corse.. there is this Aspire One Bigger HDD.. 4 gig ram Athlon X2 Neo 64.

So, I guess.. In a little bit i'm off to frys to see the one I saw there.. it HAD a dual core processor on the demo but I bought the ' same model' but single core.. So this is why I did not open it yet.. and found the Amazon ones.. Just need some imput please from the pros.

Thanks all

 

No replys, So I took it back for a refund.
