Why GFX card with more RAM?

[JG301_HaJa]

I will try ATT and RadeonPro if that doesn't work.

I have however tried with both applications before and done everything suggested
even deinstalling everything and just installing the radeon driver and operate it with
ATT but that leaves crossfire disabled since ATT in the latest version is broken in that regard.

It doesn't seems to fare well with my system unfortunately. Perhaps the solution is to
test with a monitor capable of 120Hz?

But i will keep fiddling, sooner or later i will perhaps get it to a state where it is operational.
