hi,
i know this question has been posted numerous times. did a little research on both - and correct me if i am wrong:
prescott - heats up but more L2 cache
northwood - stable but max 512 cache
i will be basically using the comp for video editing etc and so will the prescott be better? will the difference in performace be significant ?
is there anything else that i should consider before deciding ?
thanks in advance

The larger cache will perform noticably better, especially for what you want to do. I have had NO problem with heat on my pressy. I think the problem was notable with the socket 478's. I don't hear much about the socket T's having the heat problem and I can attest to that. I'd also suggest you make sure you get one with HT because video editing is a multi-task process and the HT will serve you well.
Keep in mind that the socket T's are not the hot potatoes of the past but you will still need adequate cooling. I'd suggest both an intake and exhaust fan if you go the fan route.

ASUS P5GD1
P-4 3.4 SOCKET 775
1G Corsaire PC400
ABIT RX600SE 256MB PCI-E

For video editing the presshot would be better.

I too recommend the prescott.
A note on the overheating, I have the socket 478 and have no problems whatsoever.
The trick is not to stick with the bog-standard intel cooler.
I use a thermaltake T-spark, although there are many options available now for very little money that can adequately cool this beast of a CPU!
