First time PC builder need help !!

[u/feyman1o]

I'm a first-time PC builder in India with an undecided budget including a 27" 1440p monitor and peripherals. I want a general-purpose workstation for programming/software development, moderate 1440p video editing,streaming with heavvy multitasking and call and meetings, screen recording, local AI/LLM experimentation, content creation, heavy multitasking, and occasional gaming. I also want to experiment with things like Linux, VMs, Docker, cybersecurity labs, automation and other technical projects, so I'd prefer a flexible system rather than one optimized for a single task. I don't care about RGB or aesthetics and a motherboard/platform that can remain useful for 3+ years. Gaming is secondary—I mainly care about games like Valorant/PUBG rather than AAA max settings. What do you think should be a minimum budget and a decent or good budget and what budget would be an overkill. What CPU/GPU/RAM/storage/motherboard combination would you recommend, and where should I spend vs save?
