As 3-way SLI is available and 3/4 way crossfire is coming soon, we are preparing the hwbot engine to handle these configurations better.
There will not be separate rankings for 3/4 way SLI/CF. The videocard rankings will be split up in the same as they are now: single versus multiple videocards. Charts and statistics will display the amount of videocards properly.
update 7th januari:
3/4 way sli/crossfire support has been added to the engine. It is also possible now to select the amount of processors (not cores, but sockets used). The blocked results will be unblocked shortly.
