Hi I've just installed Pro Tools 10 on my new machine, after finally getting that stupid iLock think go work - OMG what a nightmare!

Anyway, I was also advised to install 10.3 update. I'm not entirely sure why, because it seems to work anyway, but I thought I'd install it anyway and see.
Does anyone know why? I'm running mountain lion.

So my main question is,

I'm installing the Pro Tools 10.3 update and it's asking about my system configuration and I have to choose one, and I don't know which one to choose:

it says:

"Please select what PRo Tools hardware system you are installing software for, as different hardware will require different components to be installed:"

and the options are:

"Avid HDX, HD Native, or any non-HD hardware"

or

"HD TDM (HD Core, HD Accel, HD Process)"

I have no idea what either of these mean, does anyone know what I should choose?

My specs are:

iMac 21.5 inch

2.8 Ghz Intel Core i7

16 GB 1333 Mhz DDR3 RAM

OS X 10.8.2

Thanks, I hope you can help.
