Never mind but 200$ would be quite close to impossible for that.
Let's be more specific. Do you need it with monitor, hdd, chassis also?
I have combined this stuffs:
Core i3 2100,
MSI H61 motherboard,
Corsair XMS3 4GB (2x2GB) DDR3 1333 MHz,
Sapphire Radeon HD 7770 1GB DDR5,
Cooler Master Elite Power - 460W Power Supply,
Western Digital Caviar Blue 500 GB SATA III 7200 RPM,
Thermaltake V3 Black Edition.
The total would be 457$ (Amazon).
