I dont know if somebody noticed it but AMD issued a crossfire compatibility chart few days ago
http://sites.amd.com/us/game/technology/Pages/crossfirex.aspx
As most AMD users knows about AMD's flexibility when it comes to crossfire on multi GPU's
it appears that the R9 series and R7 series are compatible only same series.
Meaning, according to them you cannot crossfire 290x and 290, you cannot crossfire 295X2 and 290X.
I know there is alot of forum/users that successfully crossfire 295X2 and 290X.
I kept reading about latency issues with crossfired 290X and 290 wherein the fast card will have to wait for the slow card to render thereby adding some latency. Although, mostly visible to benchmarks but not so much thru gaming.
Reason why I am sharing this is that seeing prices of used 290X on ebay, I have come to an idea about buying 290X to quadfire with my current three 290's. I know alot of reactions from most of you guys about latency issues with PLX and bottleneck from my 4770K. I am fully aware of that. But I am considering as well upgrading to Haswell-E or Broadwell-E or whichever. Atleast GPU's are prepared.
Anyway, what do you think guys about the compatibility chart? AMD is clearly abandoning the "flexible crossfiring". Believe they ditch that idea so they can concentrate more in the issues might encounter somewhere down the road. Maybe ..... just guessing
