There's always something better, just around the corner. Arrow Lake looks to be over a year away, and then after that will just be Lunar Lake, and something else beyond that!I have put it off all summer and now decided to wait for the 149090k refresh. I don't care if it costs a hundred bucks more. ... Anyway, are you saying I should wait for the major generational leap of Arrow Lake? But that could be a year! But it does suck to build a 5- or 6-thousand-dollar PC at the end of the old generation and 9 to 11 months before a generational change occurs.
Nobody can make this decision for you, because only you know how aged your current machine feels, among other things. What I can say is the link I posted above tells me Arrow Lake is going to be a lot more evolutionary than revolutionary. Same core counts, similar power envelope, around 10% single-thread performance improvement.
LGA1700 is now a mature platform with basically all of its gremlins known and a wide array of offerings. Worst case, if you did decide you just had to have an Arrow Lake, it's not a $5k - $6k proposition to swap out your motherboard + CPU, but more like $1k. Maybe a bit more, if your cooler is incompatible. You might then get half or 1/3rd of your money back from Ebaying your old CPU + mobo.
That just my perspective. I'm not trying to convince you one way or the other, but rather to give you some aspects to consider, so that you're hopefully more at peace with whatever you decide.
