dual core

well it allows for more information to be processed at once. which means its much better for multitasking.

for right now they are not hte best for gaming because games cannot utilize dual cores. but soon games will be able to and dual cores will be very good for everything.
 
2 CPUs > 1 CPU

For now they really arn't utilized. Most games are still using a single processor. Soon, however, there will be many applications out that will be utilizing dual core CPUs. I highly reccomend getting one if you are thinking of purchasing a new computer. Good investment for the future;)
 
they certainly dont perform worse than single core cpu's in game, so there's nothing to lose with dual core. the advantages are better seen with video editing.... while performing other tasks :)
 
daul core....my friend has a 3800+ and i have a x2 4400+. I wanted to see how good it is compared to the 3200+ while the other parts to my comptuer came in. Well....i'll have to say we where so shocked that he's buying a 4200+ soon. The performance of hl2 was INSANE! I mean, he edits videos, it finished 10 minutes faster for a 30 minute HD video than his old 3200+!

I dont know if there was some other factor that may have slowed his processor but he never overclocked
 
basically... faster frequency = faster movement of information.
extra core = twice the process speed.
if you arent actually doing processor intensive applications, then no it won't help you alot. it does however have advantages in video editing and gaming though. i notice that it uses both my cores during any game i play, and quake 4 sometimes uses up to 90% of both my cores at times...
 
2 CPUs > 1 CPU
Two things
1. Assuming the 2nd CPU is used
2. Dual core != Dual CPU

extra core = twice the process speed.
Not likely. Even in theory that's not true. From a purely theoretical perspective, you'll need proper SMP for that (in addition to SMP optimizations)
