The problem with S939 now is you are basically closing your future options. Thats the only issue right now.
Intel CPUs are priced almost same that it costs in US at the moment and when it comes to mainstream CPUs they have very little premium over us price, 930 is available at just 1K premium over us pricing. You you can expect entry level Intel conroe at less than 12k.
DDR2 667 Corsair with D9 chips is priced at 12.5K for 2x1GB.
I am testing these modules and they are doing DDR2 820 @ 4-4-4-15 which fantastic and this is limit of my processor not allowing me to go more.
Last but not the least once you get conroe you can settle yourself on a platform that will last you until initial Quad core CPUs.
Same with AM2, if you invest in AM2 now you are assured that you can switch to K8L in future.
As far as the motherboard for conroe goes, the P965 based offerings are not going to be cheap. Rashi is all set to import Asus P5B dlx and its going to cost a bomb

Same with P5W DH dlx.
One of the most ocing intel board right now is Intel original D975XBX and its fast becoming favourite amongst overclockers due to it ability to clock well on CPU and also on memory front with several easy mods available for extreme overclockers and also ability to change default bootstrap by simple bios mod. ( this increases the overclocking range ).
And intel pricing of this board is fixed for next few month in india and it wont change soon.
Asroc 775Twins is still not available. i just called abacus on my way back to mumbai to as if its available and its still not. Will keep you guys updated on that.
