Does this 7950X3D have an iGPU? P.S: the table in TFA lists the 7700 as having the same 105W as the 7700X. I think that's a slight mistake and the 7700 is 65W max listed TDP instead. FWIW I'm considering a 7700 for I'm not ultra happy with my 3700X (one of the reason being it has no iGPU and I could find a passive GPU with a NVidia chipset, forcing me to use proprietary drivers in Linux and it's a major PITA for if I…

I vaguely remember that the iGPUs in the 7000 series had some trouble with Linux support. May be wrong, but do look into that. Might need a bleeding-edge kernel and mesa.

The inflation has really hit the consumer market... 700$ for CPU and over thousand for GPU... Memory is not cheap either... Not that it won't sell, but still these price points for something still called consumer start to be high. You could get a whole portable PC for same money.

my 350Mhz Pentium 2 cost about $700. So did my 19" CRT monitor..

Not with the same performance you cant...

Not even close

$700 for the Top of the line CPU is actually low, at the highest of intel monopoly period they were charging well in excess of $1000 (closer to $1700 if I remember) for their I7 K line enthusiast PC's.. Even today $700 is cheap compared to the Threadripper line AMD seems to have given up on.

Do we have an easy to find brand/line with ECC memory at reasonable prices yet?

I don't know what reasonable prices are to you, but PCPartPicker can answer your question:

Filter for the memory amount and prices that work for you.

2 x 32GB ECC UDIMM DDR5-4800 RAM is going around for ~280$ here (including a %20 VAT, so I'd assume it would be a little bit cheaper in the states). Not really unreasonable considering regular DIMMs (albeit with higher speeds like 6000) going for 400$ for the same configuration.

Generally "game detection" is done by finding apps that use full-screen exclusive presentation. Could also look for windows that are doing the "borderless windowed" thing. That should be pretty simple and accurate on its own.

Oh good catch! I didn't read that far. It's on page 11:
