[Arun the Gr8]

I need to buy a PC for 12K max. I can get a 2nd hand monitor. So tell me what options do I have with the rest of the components..

[Sam]

Athlon II X2 240 @ ~2.5k
Gigabyte 740G AM3 @ ~2.5k
2Gb DDR3 any make @ 2k
500Gb HDD from WD/Samsung/Seagate @ ~1.8k
Zebronics Bijli@ 1.5k
-----------------------------------------------------
TOTAL: 10.3k you still have 1.7k left so get UPS or keyboard mouse, speaker with it. or spend it in getting a tri core.
