Very True, that GPU does not holds well if it is just for gaming. This much VRAM will help when you are also going to be using an Application that will make full use of it. And I was about to suggest the sameI agree with @iPwnz. This is a huge amount & if I were spending this much money.., I would choose components that I want.
If you remove the GPU from this build, It shouldn't cost you more than 1.35 lacs. Rest is going for the GPU only which obviously is very overpriced. If you were to go with your components, you can build a significantly better gaming system by going with a 5600x, b550 board, more nvme storage etc.. & it will still be less than the 1.35 lac figure. That said, getting a GPU for this build on your own would be another challenge that you should plan ahead of time.
Ryzen 5600X
B550 Series Motherboard
16GB or 32GB RAM
2K Monitor and RTX 3070/RTX3080
Good Cabinet under 15K
AIO
And still this can all come under 2.5 Lakhs.
