People who slam the Prescotts should really get one & try it out first...
Sure you have to pay some attention to your cooling, but it's definitely worth it IMHO.
The one I put together ran fine overclocked, 2.8e running at 3.6 ghz.
On every test I had it ran at least twice as fast as my AMD clocked at 2.1ghz.
I didn't have every cpu to compare against, but I know that using real applications was a lot faster than anything I've ever seen before.
Do they run hotter? yes
Do they run faster? YES
Is price / performance a good ratio? YES
Tests that were important to me:
seti@home:
2.1ghz AMD 350mhz bus 6-2-2-2.0 timings
Average WU time 2hr 15 mins
3.4 ghz Prescott (didn't leave it at 3.6 to reduce heat)
average WU time 1hr 5 mins
DVD2MPEG:
2.1ghz AMD 350mhz bus 6-2-2-2.0 timings
42 minutes to complete
3.4 ghz Prescott
21 minutes to complete (same DVD)
This is not meant to be a gaming rig, it's strictly business. That being said I wouldnt scoff at playing a game on it
Of course I wish I had a northwood to compare it to, this Prescott was my first step back to intel in a long while. My customer wanted intel so I went with this one.
This is admittedly not a scientific test and based solely on my own experience. That being said I doubt there are any 64 bit AMD boxes out there doing work that beats the times of that Prescott and those times were not at it's fastest settings.
I didn't want to spend a lot of money on cooling, this was using the retail HSF and one case side fan pulling air into the case. It's a nice quiet box, the cpu temp was about 55C under full load with two seti processes running. That was totally acceptable, and of course the customer isn't ever going to do anything that comes close to loading the cpu to that degree. It's sitting there in his office running about 44 - 50C depending on the work being done.
