I still have a 5700XT I bought in 2019 (i think) for 300€ in my gaming rig. Crazy that they were going for $500 6 years later.
But to reason in other direction, unless you absolutely need cards right now, you could throw that ~$1440 in a 6 month CD and let the 4.5% pay for the tax or shipping on a 10090 XT or whatever RDNA 5 flagship when those drop in about as much time. If it lands anywhere close to what the rumors are indicating it should be a fucking monster.
