Sorry, should have been more specific. He already has the peripherals and the monitor. He only needs the CPU, GPU, motherboard, ram, cabinet and power supply.
If he is spending so much for 1440, I would suggest to adjust oled or mini led ( with more dimming zones)monitor for the best gameplay experience, specially with cyberpunk and f1.
I will not recommend a 9800X3D unless your budget is high enough to get a 5080 first. Considering 5080 is just 15% faster than 5070Ti & 5070Ti costs under 80k now, 5080 is a poor value. I myself have 9800X3D + 5080 but now the pricing dynamics have changed.
Gigabyte 5070Ti goes for as low as 77k every few weeks, was 77k in Vedant & many other shops 2 weeks back.
Meshed front case is important for India IMO but your friend’s call (that XPG one seems to have glass front).
AIO is not required for 9800X3D as well. I’m using a puny AK400 with some UV (at stock frequency) for my 9800X3D. As ambient temps are relatively low in Bengaluru, my temps are good. AG620 is good enough for up to 200W CPUs (9800X3D is 150W at stock).
That MSI PSU is a noisy one. Better to go with other A tier PSU from another reputed brand. Not as big of a problem for us Indians who usually keeps ceiling fan on but thought I’d mention it anyway.
