I am considering purchasing a motherboard from either the J7F4 or J7F2 series... most likely a 1.5 Ghz processor. I can't really distinguish which series would be better -- both mobos seem very close in features with the major difference being the J7F4 CPU is packaged in NanoBGA (WTF does this mean) and the J7F4 has 10/100/1000 nics on board. Also, the J7F2 seems to have two variations in power consumption one at 12W vs 25W.

I'm not really concerned with NIC difference or power consumtion difference, but more in regards to performance using it to play mp3's, gps nav, movies, and running game emulators in car environment.

Can someone recommend which one would be a better choice?

And i'm kind of set on one of these two models due to the price being sub $150. However, would it really be worth the extra $30 - $40 to shell out and get a 2.0 Ghz Chip instead?

Thanks for your input!
