The murder of SLI made me so angry. It was so wonderful to be able to buy a card, then a few years later buy another of the same card for a bargain price and boost your performance by ~60%.

That and increasing RAM down the road for the system itself were some of the few upgrades that made sense. Usually by the time you could buy a high-end CPU replacement, it was a "better deal" to just replace the entire motherboard/CPU combo and get a whole new computer. But a second video card, some more RAM, additional SSDs, those made sense.

SLI was ultimately killed by the rise of TAA. Interleaving frames breaks the assumptions of TAA models about the presence of temporal history. That's why NVIDIA went down the path of building a better TAA model/upscaler instead.

  TAA is also terrible and turns visuals into a smeary mess, particularly because devs keep building it into games in such a way as to be nearly impossible to turn off like in Halo Infinite.

    Nah, you hate bad TAA. DLSS is TAA too and it's actually great, DLAA is real nice, or the cool kids are doing some DLSS+DSR thing (bigger intermediate space?). Halo infinite is the poster child for fucked-up TAA, same for RDR2, you know what works better than anything else? DLAA lol. It provides a minimum floor. Games are just going to use temporal accumulation now. There is too much signal to be gained from re-using past samples. It makes things way cheaper and opens the door to extrapolation and non-uniform sampling etc. It's the least bad of all the options, and DLSS actually is quite good at weighting samples pretty reasonably. DLSS 2.5, 3.0, 3.5 and upwards are actually significantly better and that can be injected back into (non-anticheat) games and the bar will likely continue to be raised. It is a signal processing technique that recovers a lot of signal with very low "noise factor". https://en.wikipedia.org/wiki/Noise_figure https://en.wikipedia.org/wiki/Noise_figure
