You live in India right
Deep. Searched google a bit and found this site bitkart computers. you can customize your PC build on the site and the site will give you price estimation on your custom PC.
I Tried the site's builder for USD 2,500 or around 209,130 Indian Rupee with the current rates with google rate. If you picked a cheaper motherboard and M2. SSD brand you could build a pretty good gaming PC, I attached the build I picked using the site's builder totaling around Indian Rupee 213,740 or USD 2546, you could also pick a cheaper GPU and or PC Case to lower the price, however I'd not recommend picking a cheap CPU cooler, current CPUs run hot and a good cooler is a must. And Power supply is also important a cheap power supply is not good in the long run.
