OK, somethings are fixed since I own them already. I have this(http://www.newegg.com/Product/Product.asp?Item=N82E16813185062) board which is an Athlon XP Mobile 2800+ Socket. I have 512mb ram.

I'm planning on getting
HD5500 tuner
PVR500
A decent Video card(~$60)

With this setup I will not have any room to expand(internally) anyways so I want to make sure everything is going to work well before I buy the tuners and the video card(any recommendations?)

Will this cpu/tuners work fine for HD, I want the ability to record/watch SD thus the PVR500 and I want to be able to record HD if the show offers it.

Any thoughts, suggestions?
