I couldn't really find anywhere to ask this, so I gathered this would be the best place as I expect a few of you have one. I have 3 choices, the Black Magic Intensity Pro, the Black Magic Intensity Shuttle and the Hauppuage HD PVR. The BMI Pro requires extra Hard Drives in RAID 0, the BMI Shuttle requires USB 3.0, and the Hauppuage should work right out of the box. The former two may cost a little more for the extras BUT, I expect they will be higher quality than the Hauppuage. Assume I have $300 AUD to spend, what am I going to get the best quality from? I'm thinking the BMI Shuttle.

Oh, and my computer specs are
2x Radeon HD5770's
i7 860
4GB RAM
P55-UD3 Motherboard

Can I run the BMI Shuttle? You need a certain mobo or something.

On further thought, you can rule out the BMI Pro, way too expensive for extra hard drives. PVR vs Shuttle.
