if u wanna know.. 3d mark 06 kinda outdated benchmark for nowaday spec.

3dmark 06 mainly will increase the benchmark when the higher the cpu clock u got. bet me if u dont believe. compared when you OC your gc just a little bit the score will increase.

3dmark 06 also seem not fully utilize the SLI user. i tested it. i use single card n SLi. the score are almost same in default mode.

dont u know this? i suggest better u go 3dmark vantage for better pc benchmark.

about the case u had on 4870 x2 lower than the 98gtx+ Sli performance, is the nvidia chipset working 100% performance with ati gc? n will the ATI chipset will working 100% performance with the nvidia gc?

i think there is something about this that we need to find out.
