personally I see little reason to get AMD if you need dual core and willing to OC. C2D oced cannot be touched even with an FX chip. However for non OC crowd there's value to be had at 3600/3800 X2s. Especially if you look at the motherboard selection at this time for C2D vs AMD. AMD has good mb for less. in any case if you dishing out 200+ bucks for CPU, then AMD isn't a good choice but at sub 200 range the X2 3600/3800 could be a good reason to buy AMD. Another place where I'd get AMD is single core, P4s are no good at single cores, I'd definitely get AMD there. There's not much contest for AMD at single core solutions right now like magomago points out, you can get a nice combo deal on single core for like 100 bucks on AMD which is more power efficient, more OCable, faster than P4s.
