Diff has now doubled, profitability slashed.........twas nice whilst it lasted!
Just keep an eye on the kilo-watt meters...........
Haven't looked into it but I thought it's going to happen. It's like a wildfire. Part of the reason why I proposed a private forum (to share profitabiltiy related info) for people who actually post here, to avoid lurkers who distributes or even sells the info on other sites.
5 months isn't that far away, if this is the case too, mining is not profitable anyway so better to wait, unless you need it to play far cry 4

, but even then a 970 can run any title at full hd, 980 would be mandatory for those who bought a 4k monitor, i can agree on this
for cod advanced warfare, I heard it was a bit laggy, but with 2x 980 it seems rather ok (waiting far cry4 too...)
I'd say 9xx SLI is necessary if you want to keep 60fps at 4k considering how bad console ports we're getting. Just look at ass unity which requires a GTX 680 while the recommended card being a GTX 780.
CoD:AW is either have a terrible netcode or there are p2p connections between players which is borderline retarded. Either way I heard it's unplayable in it's current state because of the lag.
