HELP SPEC a video game streaming rig

[.temp]

Hey all

I'm looking to start streaming xbox360 and ps3 gaming sessions when I get back to the UK. Have been told to go down the internal capture card route...which means I'll eventually need a new rig (I don't want to drag my Antec 902 everywhere).

For the capture card I'm looking at getting a "BlackMagic Intensity Pro"

I need a rig to go with it. The rig doesn't need to be flashy at all, preferably mini-ATX to increase the portability. The online support states....

CPU Requirements

In general, you should choose a CPU that meets or exceeds the system requirements of the software application you are planing on using.

Recommended Motherboards

The following motherboards are recommended for use with Decklink, Multibridge and Intensity capture cards:

* Asus P5E
* Asus P5B
* Asus P5Q Pro Turbo
* Asus P6X58D (Bios later than 12.04.2010)
* Gigabyte EP45-DS3 **
* Gigabyte x48DQ6 **
* Intel D975XBX **
* XFX 790i Ultra **

Memory

Blackmagic Design recommends a minimum of 4GB of memory for all systems.

Graphics

Decklink, Multibridge and Intensity

An accelerated graphics card is required for use with Decklink, Multibridge and Intensity cards. A motherboard integrated graphics card is not adequate and will not work properly.

Storage

You will require hard drive storage with your Blackmagic card that can provide a data rate greater than that of the video compression you are using.

**AS I EVENTUALLY HOPE TO USE WIRECAST AS MY STREAMING SOFTWARE HERE ARE THE SPECS THEY STATE**

Windows

* Windows 7 processor: 2.3 GHz 32- or 64-bit,
1 GB RAM, or:
* Windows Vista processor: 2.3 GHz 32-bit (x86),
1 GB RAM, or:
* Windows XP, SP2 processor: 2.1 GHz 32-bit (x86), 512 MB RAM
* QuickTime 7.5
* 200 MB HD (for install)
* HD space for recording to disk
* 32 MB PCI-Express graphics card with 3D acceleration (GeForce or Radeon class card recommended)
* Microsoft® DirectX 9.0c
* GeForce 5200, Radeon 9600 or better for Chroma Key
* Sufficient upload speed (300kbps for low quality, 700kbps for good, 1.3 mb and up for HD)

I'm looking to record and stream live commentary for matches too, so do you think I'll need a sound card?

I'd preferably like to go with Intel on this...i'll have a look and see what I can think of, but if you guys can think of anything please let me know

TL;DR?

Going to be streaming HD 360/PS3 gameplay (with SOME recording too)
Going to be streaming audio commentary
Need a rig
Thinking of using internal PCI-E card

Or should I forget an internal card for now and just get a USB one?...would be less of a risk if things don't take off and I could start a lot sooner
