MacBook Pro C2D 2.16 vs. E4300 oc'ed XP desktop

I built a smallish PC a couple of weeks ago to act as a media server/ripping-encoding machine. The laptop is still used occasionally for ripping.

#1:
MacBook Pro, OS 10.4.9
Core 2 Duo 2.16 GHz (T7400), 2 GB RAM
MP4
H.264
Seinfeld Season 3 - 640 x 480
2000 kbps / 160 kbps AAC
1 pass
22-24 FPS
HB 0.8.5b1

#2
mATX w/ XP Pro SP2, 2 SATA 500 GB drives (non-RAID)
Core 2 Duo 3.0 GHz (E4300 overclocked), 1 GB RAM
MP4
H.264
Seinfeld Season 3 - 640 x 480
2000 kbps / 160 kbps AAC
1 pass
36-40 FPS
HB 0.8.5b1

I can't justify buying a Mac Pro just to do the dirty work, so I built #2 instead. It's performing like a champ.

For some reason Windows GUI 2.41/0.9.1 ran slower than 0.9.0. I'll try it again later.
