I was browsing the Whirlpool Gaming Configurations and realised they are a bit biased towards build vs buy and there isn't enough bargain-hunting in them (https://whirlpool.net.au/wiki/rmp_sg_whirlpoolpcs_gaming_con…). I have a few ideas but wanted the forum's insights…
General principle, if patient, is to wait for an ebay 20% off sale. In particular Dell do not price-jack their PCs
$500-ish Budget Gaming
Buy a refurbished i5 desktop (i5-2500 or newer, including or adding an SSD)
Add a Low Profile Nvidia GTX 1050Ti
These will crush a Ryzen 3 2200G for gaming
Here is an example refurb deal (now expired): https://www.ozbargain.com.au/node/394340
Available now is this (upgrade to 8GB ram): https://www.reboot-it.com.au/p/Used-Computers/Core-i5/Dell-O…
Or this (but better deals do get posted regularly): https://www.reboot-it.com.au/p/Used-Computers/Core-i5/Dell-O…
The LP graphics cards haven't had amazing specials the past few weeks, most recently ~$263 from ebay 20% off specials
$800-ish Solid 1080p Gaming
Actually the Whirlpool examples above are pretty solid, just replace the graphics card with an RX570 which have recently come down in price substantially
E.g. https://www.ozbargain.com.au/node/395901
If you need a copy of Windows and aren't planning power-hungry upgrades a pre-built alternative is one of these Dell's when the ebay 20% off deals come along:

You'll want to add an SSD though
$1100-ish Amazing 1080p Gaming
The Dell pre-built i5-8400 / GTX 1060 is hard to beat for price/performance when it is 20% off at $1,119:

If you want to game at higher resolutions then I think we're past the budget choices.
PCByte sometimes have some decent value packages during ebay 20% off coupon times but they also have a lot of overpriced configurations and the supporting parts tend to be weak (in particular, for higher resolution gaming you'd want a GTX 1080 graphics card or better and if you're paying that much for a graphics card you probably want a more reliable power supply).
The Dell i7-8700 / GTX 1070 is decent value at 20% off but the price of a GTX 1080 has come down enough that it's probably worth squeezing one in if you're spending close to $2,000 (recently $1719 https://www.ebay.com.au/itm/New-Dell-Inspiron-Gaming-Desktop…)
At higher price points the ozbargain approach is probably to find individual components on sale (particularly that graphics card, or if you want higher capacity SSDs) and build your own. Whirlpool forum guidance is probably very reasonable, just being selective around pricing.
As a humble bargain hunter I'd appreciate any other insights you have. In particular I'd be curious to know if anyone has found a common desktop refurb that can handle an RX570 graphics card. It would be great to find a cheaper base to build that card into but it requires a stronger power supply than most SFF desktops (and ideally a power supply with a PCI-E 8pin cable).
Unless you have specific titles in mind that are CPU bound you'd be better off buying an i5-8600K and trying to get to a 1080 IMO.
