Tell me where you could buy old processors in sufficient quantity today and please explain how a modern motherboard with sufficient RAM would hold such an old processor?
But if you want a processor without this fix, then you're in luck: from what I understand, all modern Intel processors don't have this fix yet. And they're very well supported by motherboards.
And by the time the current crop of processors becomes unavailable, I suspect newer processors will be much faster than anything currently available.
If that's not old enough, there's also this: https://ark.intel.com/products/series/79666/Legacy-Intel-Cor...
