I ended up giving up on the original dual core motherboard/cpu I bought for this, and just used the old Pentium 4.
It, of course, couldn't play HD youtube videos, but that was ok, as I was unemployed at the time
Anyway! new job, so I bought a (very) second hand Dell dual core computer with no hard drive, for $60, and set that up instead
plus it came with a Windows Vista sticker on the side, so we'll call that a legitimate version of Windoze
Yes, old thread, but I've concluded that no matter how fast the single core cpu, it won't do HD youtube.
