PC build, Advice please

[Namens_Are_difficult]

Budget (including currency): around $2000 - $2750. AUD

Country: Australia

Games, programs or workloads that it will be used for: The computer will mostly be used for gaming (including but not limited to ,fps's: rainbow six sige, overwatch, Doom. Sim's: American truck sim including wheel, pedals and gear shifter, the crew, then some more simpler games such at colane survival, jackbox and many more.) and maybe in the future photo editing as I do like photography (but definitely not a priority) it may also be used to do some very minor school work like word dox but I don't think it should change much.

 

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): i have selected a series of parts that may or may not sound good,. all the parts that i have collected are found on the Australian tech compony "Scorptec" and would like to buy from them if possible as i believe they assemble it as well. My current setup is a Oman gaming laptop with a i7 8th gen CPU, Nvidia rtx 1050 GPU, 16 GB of ram and a 15" screen, I've had that laptop since years 7 (now in year 11) I'm definitely not picky about performance as i am used to constant stuttering, same with video settings i don't mind if i have to change the setting to low ore medium just to run the game. i will be using a monitor that my brother has, as he has very rarely used it and has allowed me to take it, the monitor is a LG UtraGear QHD IPS 1ms Gaming Monitor with G-Sync® Compatibility, refresh rate: 144Hz Resolution: 2560 x 1440.

 

so all I'm asking is there any advice for me. if there is anything I should change.
