Question / Help Dilemma! Dedicated Streaming PC/Laptop?

[binaries]

I have been clearing up my place and managed to dig out stuff I no longer use but I'll cut the story short.

I have decided to set aside a dedicated streaming machine. Right now I am stuck between two choice.

1) Alienware M17X QX9300 8GB Ram laptop

Pros: It is a laptop so I can keep it anytime I want and less clutter and prepration needed as compared to Choice No.2

Cons: I am afraid it will not be powerful enough to handle OBS capturing it at 720/1080P 30/60 FPS.

2) LGA 1366 i7 Extreme 980X + Asus Rampge III Extreme + 12GB Ram

Pros: Very very strong 6 Core processing machine.

Cons: I will need to downsize the huge LianLi Tower case it is in right now and I definitely I want it to be a SFF system for space saving reasons. That reason alone means I need to buy a SFF case, an outdated lga1366 matx and then to set everything up at the end of the day.

- I personally am leaning to the Alienware QX9300 since I do not have to do anything to have it be a ready made dedicated streaming system but I worried that it might not be powerful enough to do its job.

*Already owned Avermedia LGP.

Any advice on which to go with?

Actually its hard to say. The i7 is probably much better than an old C2Q, but since you already have the LGP, there is no benefit in using a desktop anymore :/
I would do this: Try it on the alienware laptop, that means just installing the lgp and setting up OBS. You can easily find out if it can do 720p30 or more.
