AMD FX seems ludicrously cheap - any reason not to go for it?

Currently on Amazon, the FX-8350 can be bought for £73.48, compared to (say) the Ryzen 7 1800X at £229.13.

So for less than a third of the cost of the 1800X, I can get the same number of cores, clocked significantly faster (4.0 - 4.2GHz over the Ryzen's 3.6 - 4.0GHz).

The FX has only half the L1 and L3 cache, though it has twice as much L2 cache. And of course it is limited to DDR3 (1866MHz max, not sure if any mobos will allow OCing to 2133).

Now given that I don't care that I would be buying an older generation CPU (I wouldn't be interested in upgrading/reusing anything later except maybe adding more RAM, and DDR3 isn't going to disappear), is there really any reason not to go for the much, much cheaper CPU?

Thanks

FX are horrible in terms of ipc - forget about frequency, cache and all you think you know. Its comparing apples to oranges - they are different architectures. An FX-8350 is not a true 8 core cpu, its more like a quad core with HT, a very SLOW quad core. An i5 2500k stock is faster in games than a FX-8350, Ryzen's IPC sits somewhere between intel's 4000 series and 6000 series (7&8K are the same arch as 6k) so even a 4 core Ryzen chip will smash a 8350 without any problems. Also you can forget about fast DDR3 on Piledriver arch because it doesn't do you any good.

Just don't do it, there's plenty of reasons not to....old architecture, semi-8 core, uses slower memory, etc. Any of the new ryzen will destroy it in most, if not all, benchmarks. It's a dead platform, that's all that needs to be said realistically.
