MCPC/Moderate Gaming Rig.....$1600

Hey Guys, I wud like ur opinion on my build here. I live in india and all the old core components are very cheap and the latest are over priced.the peripherals too are very high compared to the their counterparts in US. I wud like a moderate gaming rig which can play like NFS and GTA (even nxt editions in the future). i'm in no particular hurry and i plan on buying in Dec.

Shud i wait for DX10 cards or not? will they b below $250?
