Country and store of choice?
Screen resolution? Probably 1080p with that budget.
I'd say start by looking at what is available to you. Probably want something with an GTX 1660 Super/Ti, RTX 2060/3060, RX5600XT
CPU of choice today is going to be an i5-11400/11500/11600 or an Ryzen 5 5600X at the top end. 10th gen i7 might be relatively cheap as well.
If that combo is out of budget, than maybe a Ryzen 5 3600 / GTX1650 Super
Going to want 2x8GB of DDR4 3200Mhz (minimum) for AMD, 2666Mhz for Intel or better.
