As we approach a new era of gpu usage, and gpu scaling becomes tighter and better than ever before.. I think now is the time for Nvidia and AMD to start planning for the next year or two to release our cards from the 4 card restriction.. they have both done an excellent job this last ten years, congratz kudos and fanfare deserved!
now we are *firmly* in the 2010's.. time to look ahead to the next few short years, and I feel opening up the protocol to however people like use their hardware and putting the driver to work instead is the smart way to go.
more powerful cards yes.. thank you thank you yes! but also a choice about how we wish to assemble our system.. its smarter for you to open up mid-range cards.. why? if you don't take their money someone else will with another component.. 4 way 5 way.. as many ways as motherboard manufacturer/chipset manufacturer can fit on a board, as many ways as customers like.
Imagine a horse, a thoroughbred, he can run the track in record time, but a trap brace can go much faster.. can be funded over time, and do not need to be thoroughbreds .. I would like to own two thoroughbreds, but money does not allow, and as such is a pipe dream, which comes with a luxury yacht and two Filipina models and it's this kind of thinking that may be holding back the industry, 'make an elite' with price points..so another company from another component field receives my money.
peace
