For the GPU benchmarks, cpu catagory doesn't yield points. You should label the cpu portion of the benchmark as the make/model of your cpu. The x2,x3,x4 indicates the amount of cpu sockets being run on the motherboard.
Use the correct cpu brand, name, model. Indicate in the notes or discription area if u want, the number of cores being used, or better yet, spam that description area with
www.overclockaholics.com as if you make it in the top 20, it'll be listed on people rankings page at their forums.
Regarding the Fusion software, I haven't seen anything regarding it but if it only disables other programs in windows and does not directly alter, hack, change code within the benchmark, it should be o.k.
