So a little history, I was an EARLY adopter to MCE and to this website actually.  But I was incredibly frustrated at how fragile the solution was during the WinXP days.  So I have been gone for like 2 years just using Comcast DVR.  I want to give this another try, install Vista Ultimate but also I want a HIGH END HD TV Tuner so I am looking for options.  Do I just go to ATI and get the most expensive adapter?  Thanks everyone -

Current system:

• 3.2Mhz
• 1 GB RAM
  
• 225GB Primary Drive, 500GB secondary drive
• Radeon X800 XT Display Adapter

Its funny looking at these specs now.  Back in the day this was a smoking hot system and now, I might be better off just buying an off the shelf computer at Costco vs trying to upgrade this system.  Thoughts?
