What's ur present config? If its not very ancient, I suggest u hold on a little bit longer. Prices have fallen a bit and they will fall further when the new socket 939 64s are launched in India. Waiting for the 939s makes sense as they are soon going to replace the present 64s. But if u still want a 64 right now, u should be able to get one for around 8 k plus.
btw, one prominent advantage of the 939s over the present 64s is support of dual channel memory..ergo, better performance. (don't mind the "ergo"s...I'm a Matrix fan!).
