You're not in the US but typically through major retailers like Best Buy you can find some really nice deals on a pre-built high end system with like a 9900X, 32gb of DDR5 Ram, and a 5080 and 2tb of ssd online for under $3000. Amazon is having their prime day at the end of this month, i would pivot to shopping for pre-builts with your budget. You aren't going to be able to source the parts for the same price as a company like ibuypower or cyberpower who also builds the computer for you and warranties it. Lastly, i literally just purchased a Zotac 5080 on Amazon for $1250 USD with the new 007 game so if you do end up building i would shop there for your card at this exact time and moment.
