CPU upgrade... or not (best choice)?

[Morutimeru]

I recently replaced my old mobo, an AsRock 880GM-LE for an Asrock Extreme3 R2.0 because I got a second 6850 so I could use it for a crossfire setup. So, I'm trying to build a new gaming rig for my little brother with my old mobo. I'm currently using a 720BE with 4th core unlocked and overclocked to 3.7Ghz stable with a temp of 38C while idle. So, my question is, should I upgrade to a PII X4 955(US$120) and use the 720BE on my brother's setup or should I stay with my 720BE and buy another 720BE(US$72) for my brother and save US$53?

Geeze! He's already up to stock Phenom II X4 980BE speed... with a Ph II x3. If his temps and speeds are for real, he must have a pretty cool system. My stock 980 idled warmer than that in a HAF 912 with extra fans.
