-Amen on the ebay buyer policy. I've stated a few times now that it's basically the only place I'll go to pick up used parts.
Look forward to hearing how the 6800 works out. I've fired up a few of the more taxing games I own @ 1440p (DX: Mankind Divided, Arkham Knight, Titanfall 2, Fallout 4... I know I know not the newest test suite) and holy crap the framerate is basically locked to 144fps and the card is rock solid.
Freesync is also an absolute game changer in terms of making everything feel even smoother. Love the OC options built into the driver as well.
AMD done good on RDNA2 by my current estimation, and for the price vs the NV competition it feels like a no brainer at the moment.
I have been on my soap box about Freesync since 2016; it changed budget gaming.
On Arkham Knight: I am doing a playthrough since it is Halloween themed. I was wrong about Man Bat. It may have been an Easter egg originally, but it happened to me the other night. So if he didn't try to jump scare you already, he will.
On Fallout 4: Are you playing with mods? Because the vanilla version can get flaky, if you exceed 60fps, the game engine doesn't like it. I read there is also a ray tracing mod in the settings now. I will fire it up tonight and try it. I also read it is probably just ray marching SSAO. Whatever it is, it is graphically demanding. I did not see any RT reflections in the vid I watched either.
The 3DMark stress tests will catch a lot of issues, not just on the GPU side but system wide.
You can change the number of loops in the advanced version. My personal observation is that if it doesn't fail within the first few loops, it will not fail.
Right on. I have more hours logged in 3DMark than many games in my steam library. I go through a lot of hardware. It is the most efficient way to evaluate baseline performance and stability. It goes on sale for $5 on Steam frequently, no reason for DIYers to not own the full version.
On topic: There are some good used deals out there. For NIB, AMD pricing is attractive on some AIB models. Nvidia can suck it on the lower tiers. They don't have a single card worth considering in the $300 and under range, where most gamers live. Of course many of those same gamers have been gaslit so hard, that they will overpay for Nvidia cards anyways. Tragic really.
