First world problem.

[SkillTim]

I now own a Palit RTX 3070 (£530) and a Zotac RTX 3080 OC (£850).

I mine Ethereum all day apart from playing Fortnite each evening. Spec below.

The 3070 is all I need for Fortnite but I can mine 50% more everyday with my overpriced 3080.

Do I sell one? Which one? Do I make a purely mining rig?

What would you do?

Who pays your electricity bill?

 

[SkillTim]

Me. But I also have PV cells so elec is free during daylight.

Mine Ethereum with both then buy the 6800XT and 6800 on their respective launches. Update this thread.

As above,would be great to see how they all perform

Use both cards and mine away, might need a better PSU though if you want both in same system.

I get 63MH/s with 3070 (143W) and 98MH/s with 3080 (230W). It would be a separate system. I'd like to know 6800XT too but looking at the RAM spec I doubt it will beat 3080.

LOL, great idea (albeit for out selfish reasons)!

Nah you can undervolt them and dial in for great power efficiency. The CPU and RAM will be getting minimal use and a trickle of network traffic is all.

I've decided to keep both. The 3070 will just be in a dedicated rig that will just be on in the corner once it's mining. Had enough components lying around to build one up. Apart from a 650W PSU that I've got coming tomorrow for only £36. I couldn't be dealing with selling the 3070 for only £50 profit when I could be mining and it pays for itself after 2 years. Not buying 6000 series.

Looks like the 6800XT is only as good as the 3070 for mining. Video shows that even after tuning it he hits 63MH/s like my 3070!
