you should get it for around 6000 to 7000. Don't know if you will get anything below that because vendors don't usually keep the cheap processors in stock. If that is out of your budget, look for the x3 processor, i believe on some of them, the fourth core can be unlocked..
So budget less for CPU and more for GPU if gaming is your goal
is "5000 INDIA IN" your budget for just the cpu, or for everything? If it is for everything then I think you can forget crysis. You'd be lucky to play farmville. At any rate you should just stick with an athlon II X2 240 (or 250 or 255 or 260 or whatever is cheaper). Yes a phenom is a bit faster for games but if you go cheap cpu now you can upgrade to bulldozer later if you get "BD compatible" motherboard. In the meantime, more money into video card will help more. Just be sure to overclock the athlon.
