It looks like u r not a frequent up-grader (ur old one is 5 Yrs Old). rohan_mhtr's suggestion is gr8, but I am suggesting u a little future proof solution, like Quad core processor. Here goes my suggestion
- Processor: Athlon II X4 620 2.4 Ghz @ 5k
- Motherboard: MSI 785GM-E51 @ 4.6k (AM3, DDR3, 4200 Onboard Gfx without sideport memory)
- RAM: G-Skill 2GB DDRIII 1333MHz - 2.6k
- HDD: Seagate 500 GB SATA @ 2.4k
- Cabinet: Zebronics Bijli @ 1.2k (ask vendor for it without the SMPS)
- Cooler Master RS500-PCARA3 Extreme Power 500W @ 2.8k
- Gfx card: XFX 9600 GSO 768 MB DDR2 @ 4k
- LG DVD Writer @ 1k
- Speaker mosue and keyboard-around 2.5k
price is around 26.5k. Here I didn't suggest a high end card because DirectX 11 cards are already here, so don't waist money on a card of previous generation. If u can wait for few days at least for the Graphics card. Probably price of HD 5770 will be a gr8 buy, if its price is reduced within 7.5k.
I suggested Qudad core because in most of the applications, u get benefit for the extra 2 cores present. Games are also getting optimized for multicores. So Athlon X4 will be a future proof solution. And for the board, if u r buying a discrete Gfx card, there is no need to buy a Mobo with dedicated onboard Gfx memory. So I have chosen the MSI board, which will save around 2k.
