If I can sacrifice some of the parts to take them cheaper, which one of them can be replaced for cheaper one (for example) and not have high impact on the performance?
personally i wouldn´t recommend to change much if you can afford it .
however if saving is necessary than you can get by with cheaper m.2 drive ,
cheaper case and power supply and lastly with an older video card like 7700xt .
while 7700xt is basically as fast as rtx 5060Ti in straight rasterization
you would still be giving up more modern features - frame generating
capabilities of 5060Ti are superior ,
DLSS 4 is much superior to an older FSR3 for example
5060Ti also has additional 4gb of VRAM which may come in handy in some future games
and also if you want to try ray tracing in which case 5060Ti is also superior to an older 7700xt
the gpu is the last thing i would touch and compromise on
because it will determine the gaming performance of your system the most .
5060Ti is also not perfect by any stretch of imaginanion but it is the best card you can fit into your budget .
rtx 5070 is around 35% faster on average but it also costs some extra cash .
