I was recently given an asrock 939 and i have been looking around at possible cpu's to go in it... so the only cpu's i liked were the 4400 and 4800 as they have the extra cache but is the extra cost of the 4800 worth the trouble ???

you could always just bump up the FSB on the 4400 to make it a 4800

I bought a 4400 earlier today :D

If I remember correctly it's only a 200Mhz difference. Hardly worth the extra cost.
