Which graphics card(s) do you use with AmigaOS 4.x (in 2017)?

Worthwhile effort, thanks for collecting the data. I've answered the survey, but to elaborate a bit: I use a Radeon 9250 on my AOne-XE because as far as I am aware it's the best option for that machine. If there's a way to use something better I'd love to learn about it!

The 9000 pro is the best card supported in Warp3D.  It has a higher clock rate than the 9250 models and also has a 128-bit memory interface while some of the 9250s do, many only have a 64-bit memory interface.

You can run a low profile PCIe card in one of the 33MHz PCI slots for more recent options.  The highest tested card I know of is the 4670.  It gives you the option of running 2 different displays at once and better 2D performance, especially with applications that use hardware compositing.

In theory Radeon SI based hardware should also work which would open up the option of faster 3D hardware and also the ability to run Warp3D Nova applications too.  However there may be a compatibility issue with Uboot like in the Sam440 series.  Is there nobody out there with an XE that has access to suitable card for testing.

The most recent video cards that work on the Sam440 a the HD6000 range for which there is no current Warp3D or Warp3D Nova driver.

...but this intrigues me! How is that possible? I assume some sort of adapter is required?

This type of adapter with PEX8112 bridge chip.

A Video card designed for use in low profile system can then be plugged in.

As Hans said, there are a few caveats.  You can't use them in the 66Mhz slot or with A1 boards that had the DMA fix applied.  It's interesting that Eyetech never officially endorsed the fix with Alan Redhouse warning that there may be unforeseen consequences.

I agree that the best option is to upgrade to more recent motherboard with PCIe slot.  If your thinking of upgrading you might as well try it since if SI cards turn out not to work you'll have an excuse for upgrading to a new A1 board that the card will work with and if the card does work with the XE you've also increased it's resale value.

R7 240 makes my Sam460ex hang

Which version of the RadeonHD driver are you using?

[Rob]

There is also a PCIX to PCIe adapter and they work with 66mhz. More expensive than ordinary PCI to PCIe adapters. PCIX is backwards compatiable with PCI so you can attach that adapter to ordinary PCI slot.

It will still only work at 33Mhz speeds.

Still wondering is it possible to get working Radeon HD card with working 3D to Sam 440ep Flex.

I've read that an updated Uboot would be required in order to support Southern Islands based cards.  Is there any word from Acube on this?  They last updated the Sam440 UBoot back in October so support for the SI cards isn't completely out of the question.
