Coreboot gamers?

Hey any other coreboot gamers? What are your specs, games do you play 
and on what settings?

Me:
I purchased my D16 specifically for IOMMU-GFX VM gaming, I have a 6274 
with a geforce gtx 780 and the new highly multithreaded games work great 
on it - right now I am playing battlefield 1 and wargame red dragon on 
high settings. I do want to get a 6386 or dual 6328's so that I can play 
older games though due to my CPU's crappy single thread performance.

Does anyone use Crossfire xDMA? It has dual 2.0 x16 slots and PCI-e ACS 
so it should work (and people have reported it does with the vendor bios)

I don't play often, and some of the times, it's to test if the GPU
still works fine. I only play free software games, and I don't have
enough time to investigate games that are not packaged in the GNU/Linux
distribution[1] I use.

As the games I test/play:
- Xonotic
- Supertuxkart

I like a lot some other games, but they are probably not relevant here
because they are not that demanding with reguard to computer
specifications.
For instance Battle for wesnoth doesn't even require 3D acceleration...

In the computers I have[2], the i945 thinkpads are too old to be able
to play recent supertuxkart versions on my distribution[1].
I didn't test gaming extensively yet on the Lenovo Thinkpad X200 as I
would need to go buy more RAM to do that: 2G of RAM isn't enough to
some of the more demanding games I care about.

I don't have my desktops here, and I don't remember the GPU models, I
only know that they are supported by nouveau and work with free
software firmwares. I use fanless GPUs to avoid them making too much
noise.
The nice side effect is that nouveau doesn't need to handle power
management to make use of them efficently.

I tested supertuxkart on the:
- Asus F2A85-M PRO
- Asus M4A785T-M

While I'm able to play, the ports are not complete yet and might
require additional hardware such as:
- USB Ethernet card in the case of the F2A85M PRO
- USB Sound card in the case of the M4A785T-M

It would be interesting to see how the free software linux drivers
handles it too:
- Nouveau doesn't seem to support[3].
- Radeon doesn't seem to support it either[4].

However I wonder if SLI/Crossfire is still stricly required to be able
to efficently use several GPU in a computer:
It might be interesting to see if there are (less efficent?) ways to
use several GPUs in the same game with GPU offloading / render nodes.

I personally have 2 nvidia GPUs so it might be worth investigating it.

I would need to add support for the F2A85-M pro for the second pcie 16x
slot first though.

You could get an ExpressCard eGPU for your x200 or x220's, I used to do 
that and it works decently.

I have always wondered what comes in to the porting choices of people, 
how come you are porting a 7xx series chipset board instead of an 8xx or 
9xx? (as they are better, newer and support IOMMU)
Or why leah had the KGPE-D16 ported and not one of the better newer 
(2014) Supermicro boards with dual northbridge (so way more pci-e lanes 
to go around) and onboard SR-IOV nics. (82576L vs D16's 82574L)

I game in a windows VM, so I would be attaching both cards to it. I 
would be getting radeon as nvidia doesn't like FOSS or IOMMU-GFX on 
their "consumer" platforms (see the code 43 "bug" they introduced)

I was wondering how to overclock the CPU multiplier or BCLK  or adjust
vcore voltage using coreboot as most gamer motherboard will do. I'm using
T420 with coreboot, and sometimes the temperature goes too high. I'm
thinking about lowing vcore may help a bit?

Cheers
