You say neither would be a significant gain but honestly anything current is a huge upgrade for them as they only have a GTX 960 and GTX 670
and no I didn’t. If you read my last message in that thread I had bought a RX 6600 but I still need one more GPU and at $200 the 1070Ti didn’t seem like a bad deal.
Thank you for the update and answering my question.
The reason for asking the question is most people who ask for advice often take action but don't follow up summarizing what they did. This isn't specific to TPU but pretty much everywhere on the Internet for everything: cooking, home repair, Linux system administration, buying cameras, et cetera.
I don't remember what every single person posted in every single thread so it's possible that any given person might have posted a follow up elsewhere. This happens rather frequently. Some people essentially ask the same question multiple times in different threads and don't summarize where they stand based on what comments they have been provided in other discussions.
As for going around in circles about the RX 6600, why don't you explicitly state something like "I have an RX 6600, am familiar with its capabilities but am looking to buy something cheaper for more modest performance"? That would have saved you and many commenters here dozens of minutes of time typing and reading. If you made that statement in your original inquiry, there would be half the number of comments yet they would be far more focused and helpful.
Nowhere in this thread do you explicitly state a budget even though that appears to be your primary consideration. The most logical place would have been the initial post with something like "I'm upgrading a PC with a Dodgy Bros. UltraMax MF 420 Xi for a user who doesn't game much other than a few hours of Magic The Gathering per week. I've been offered a 1070 Ti in ____ condition for ____ dollars from a seller with ____ reputation. Can I do better with a maximum budget limit of $____?"
Like I said, not everyone here has memorized every single post you've made and saying "well I mentioned it in this or that thread" is meaningless since you could have easily changed your budget up or down.
One thing I do note is that extracting information out of some people is like pulling teeth.
As for DLSS, it works better when outputting at higher resolutions because you have more pixels to start with. DLSS Balanced or DLSS Quality often works great for Ultra 4K gaming. DLSS image quality does suffer noticeably at lower resolutions like 1080p. I have an RTX 3050 driving a 1080p display but I don't game on that build.
You have been provided enough information in this thread about where the 1070 Ti stands relative to other graphics cards, both current generation products and older models. At this point it's up to you to say "Yes, I will spend my money on this" or "No, I will wait for something else."
