What a wonderful thread. I just picked up a Dell OEM 6800xt second hand. I am currently quite happy with the card.
Pros:
- Relatively compact three fan design, smaller than the MSI Armor 2x 980ti it replaced.
- Very understated design (Not a big fan of the gundam coolers on a lot of AIB cards).
- Good noise levels, no coil whine or fan pitch
- Good temps given size of card, at stock card runs about 70c under load and overclocked the card hits ~80c
- No issues OCing card up to ~2500mhz
- Stable
- When buying second hand, these cards will typically sell a bit cheaper than AIB variants that perform similarly
Cons:
- Just an average ho hum 6800XT. Consistently benches into the "average" zone in 3D Mark for example, even with an OC applied.
- For some people, the design of the card is super basic. Just a black rectangle with a light up "Radeon" logo on the side. Green PCB under backplate.
That said before purchasing I did a lot of reading on the Dell OEM 6800XT and the general agreement was that it was an unusually well built OEM card. Dell might have been anticipating a much hotter/power hungrier card than what was actually delivered to them.
In the end, like any card, do your research and make sure the model and brand of card you're getting have a good rep.
