the cheapest conroe is $183, thats about Rs 9300+ taxes in India, now add the retailer profit to it, & it sure will be about 10.5k at start, & since C2D is not much available in retail this year, the prices won't come down anytime soon.
Infact, this is a good time to buy Athlon 64 3800+ X2, for Socket 939 & AM2, the prices are down too, & this CPU is now Rs 8.5k only, gives performance only 5% lower then E6300, it is an already proven architecture. All hail AMD price cuts
. couple it with a Asus A8N-VM/M2NPV-MX for AM2 motherboard, & u can get a vista premium ready, solid budget system at really good price, well within 14K, u can use normal DDR400 with ASUS A8N-VM or u can buy DDR2 for M2NPV-MX, ddr2 is costly, but since now, both Intel & AMD have made transection to DDR2 only, the prices will rapidly fall down
at start, D965SS will cost about 6.5-7k, due to low availability, but with time, & availability it will come down to 5k in 4 months only
Edit : just inquired, Another option is Gigabyte GA-K8N51GMF-9-RH for Socket 939/GA-M51GM-S2G for AM2
My advice, if u have some more money to buy socket AM2 based system, in case u cannot find C2D then do so, buy socket 939, only if u r tight on budget
