So here's the thing: I've built SLI systems every generation dating back to the 8800 GT, and in general I've been pleased with them. Yes, the complaints in general were valid (although often overstated), but on the whole I've always found it worth it to pay for depreciation on a second GPU to get a decent performance boost in a good number of the most graphically intensive games. Now fast forward to this generation. I'm a veteran of early adopter stuff, I knew not to expect to be blown away by the RTX stuff, and that it would be a massive performance hit. Of course, the way NVIDIA sold this was that now SLI would be even more important than ever . . . increased support, a new bridge with new link technology. In theory you drop the extra money on the second 2080TI to get playable framerates with the RTX stuff. Whether it's worth it to pay that much for a bit of extra eye candy is of course a questionable value proposition (for me it is because I make plenty of money and gaming is my main hobby), but it's out there for everyone to make an educated decision. My problem is that NVIDIA has basically pulled a bait and switch -- out of every single game with RTX support, literally none of them support SLI or mgpu. Not a single game as far as I can tell, not even with user hacks. The games that support SLI/mgpu and RTX effects won't work with both enabled at the same time. Beyond that, there has always been talk of "sli has no support," dating back a decade or more. But this is really the first time that the hyperbole has been reality. Lately it has been AAA game after AAA game with none of them having any support. I just keep it turned off now for the most part. The only utility at all I've gotten from it has been older games . . . there are some GTA V graphics mods that can actually stress a dual RTX 2080 Ti system, and Ghost Recon can benefit from two cards. But I have to say, I'm really disappointed to see a new SLI bridge come out with promises of renewed support, and then right after, basically all support gets dropped. Division 2, Metro Exodus, etc, I could go on. And many games that have no support now had support in their prior iterations.
