I'll wager a newer I7 thru I9 Intel or AMD equivalent, 32 gigs of RAM-preferably DDR-5 I suppose, Eagler's 3070TI or something close, a good power supply like what Eagler shows in his profile thingie and most importantly, a solid state drive will get you a similar lifespan going forward.
Hell, buy an exact copy of what Eagler is running, that's a good looking rig.
