[coreboot] 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)
