I know this isn't exactly the advice you were looking for but I would honestly sell the 570's, because there current price is extremely high and invest that money into a 2nd 1080ti. The 570s days are numbered but the 1080ti will be a good investment for the future. If you sign up for the alerts on nowinstock you can snag another 1080ti for $800-$900 and you could potentially sell the 570s for $300+ a piece. Just a thought.
