Like I said, you're never gonna practically see a difference when it comes to games. You won't even run into SLC cache issues since your internet speed will be the bottleneck there.
TLC vs QLC write cycles don't matter for games, once you install a game, it will stay until you finish it or get bored of it.
You spending 500 more for TLC and losing 2 years of warranty seems like a bad choice to me. This is a game drive right? Just download all the games again if it does fail. You have 5 year warranty anyway.
But for boot drives I would always suggest TLC drives with DRAM
Edit: If 500 was worth it for TLC, then why not add another 700 to get
KIOXIA 1TB EXCERIA with DRAM (from Toshiba) as well? See, this is a slippery slope. There's always a better drive out there for just a little more. Get one that serves your specific purpose
