Yes I will definitely overcloack the processor and ;therefore, I will replace the mobo by a gigabyte z87 one and will also replace the ram with 2x4GB kingston ddr3. But still I have a case to decide. Can you recommend a good case in 2-3k? Will a "cooler master gx 650power supply" be good?
I will not recommend cooler master as a PSU choice. Corsair is a lot better in that regard. The money you'll save from not getting Corsair Vengeance will go towards a better quality PSU. Many people underestimate the importance of a good quality PSU. The PSU should be chosen in a way so that it not only has enough power to power up the entire system, but have ample breathing room so as to enable future upgrades go as smoothly as possible. You don't want to end up upgrading your PSU 6 months down the line. If you have the means of getting this PSU from abroad, I'd highly recommend you do so:
Compared to GS series, the TX is a lot more sturdy and has better quality components built into it. It will last you at least 2-3 generations with peace. It may cost a bit higher, but for such a gaming system, I'd never compromise on a PSU, even if I have to delay the purchase of other components, as it has to be the best in its price/ performance & class as it has to bear the burden of the entire rig. You might be able to find better options online, should you opt to get it from someone abroad. Or if you can find it here, then definitely get it.
Also, instead of getting it later, grab the board right now and delay other components for the time being. The base must be built perfectly the first time you're going to build a new rig. Otherwise it'll bring you lots of headache and reinstallation of windows and such should you stick with your current plan. Divide your plan in 2 parts. First grab:
1. The Processor
2. The Board
3. The PSU
4. The Case
When all these 4 are settled, then you can plan the other components accordingly. These 4, if chosen wisely, won't need a change for a long, long time. Speaking strictly from personal experience.
For case, which one do you need ? Mid-Tower or Full-Tower ? For Mids, I can safely recommend CM 690 III. For full tower though, it will become more costly. Break down your cost for these 4 parts first, then decide accordingly which stuff comes in first after these 4 are done with.
