-Faster stock clockspeeds then intels when comparing prices..
-Better 64 bit cpu's then intel. But then again, 64 bit applications will only begin to hit the market in ATLEAST 1 year..
-Quick to overheat. Especially in the summer. Stock heatsink/fan will Not cut it if you are trying to run low temps.. Do not even think about OC'ing an AMD to any significant speeds with its stock heatsink/fan.
-HT ready, HT is not great, but its an option. What HT does it simulates anoter cpu, often called a 'Ghost' cpu, and allows for much better multi-tasking, although HT is situational, it is still an option.
-Higher FSB speed.. almost double. While 800mhz fsb is overkill, it still has its advantages over 400mhz fsb.
-Easier to overclock due to the fact that intel cpu's are generally smaller chips, resulting in less heat output. You can do well with the crappy heatsink/fan that comes with intels.. My cpu runs at 38-40c idle and 42-45c on heavy load.. very nice temps for stock hs/fan, considering im in newyork and its friggin hot!
-Costly, at stock speeds, getting an intel to match an amd's stock clockspeeds will cost you 30-40 bucks more.. i'd say the 3200+ 2.2ghz barton is equivalent to the 3.0ghz northwood, but the 3.0ghz is about 20-30 bucks more..
-Longer pipelines lead to slower performance when compared to the shorter ones which amd's have.
It all depends on how much you want to spend. I spent 400 dollars on my cpu/ram/mobo and it runs just fine, I am a hardcore gamer and couldnt be any happier. When the time comes, I will OC my cpu, and the good thing about intels is they OC like a dream. No overheating concerns if you take the proper steps.
Also, lets not forget.. if you buy an amd and are concerned about heat, you will have to spend 40-50 dollars on a good heatsink/fan anyway, thus putting the price range at a 1:1 ratio between amd's and intels. (I am talking about xp's and p4's, I do not know about 64 bits)
So, Am I being biased? slightly, yes.. I am not no fanboy, but I just like intels, despite the fact that they can be a bit pricey, Its not an issue for me. But what I have mentioned above are all facts.
