Planning to build my home desktop machine after a gap of about 10-12 years - appreciate any advice the experts can offer:
Apart from general usage, I intend to play Dota 2 occasionally. I have seen the newer processors can support Dota 2 at a decent fps so ideally, I wouldn't want to spend money for a separate GPU
Processor: AMD Ryzen 7 5700G (spending $150 AUD extra for the better graphic chip on this one)
Motherboard: MSI MAG B550 TOMAHAWK ATX AM4
RAM: Crucial Ballistix 16 GB (2 x 8 GB) DDR4-3600 CL16
CPU Cooler: Coler Master Hyper 212
PSU: MSI 650W 80+ Gold Fully modular ATX
Storage: Western Digital WD Blue SN550 NVMe SSD - 1TB
Case: Cooler Master N300 ATX Mid Tower Case
I have read the newer AMD processors require a BIOS upgrade for the B550 chipset, but I believe for TOMAHAWK mobo you can upgrade the BIOS without a CPU / RAM
What sort of budget are you looking at?
Perhaps there isn't going to be that much saved doing it yourself (unless part of the reason is you want to do it yourself) and just buying a pre-build from BPC/Techfast/Etc.
I'd say what you have is a $1,350 build at absolute minimum prices unless you are finding exceptional deals here and there, then you will probably still cop shipping charges here and there. If that's the case, these two for a little more might actually be worth the dedicated GPU and 2 years build warranty that comes with it.
Option1 10400F/3060 - $1599
Option2 10700KF/3060Ti - $1899
Certainly this from Techfast with a 1650 coming in at $1,500 if you up the RAM to 16gb and SSD to a 1TB NVMe will blow the 5700G out of the water.
Option 3. There really would be no comparison between integrated and a dedicated gpu even from a base model 1650.
