Jetway & HIS HD3870X2 vs HIS HD3870 Turbo CrossFire
 

CrossFire, Scalable Link Interface, ... for quite some time now we have multi GPU solutions available, now after multiple releases of mainstream video cards both video card manufacturers NVIDIA and AMD bring us a dual GPU mainstream solution to compete in the high-end market segment. Today we'll be looking at the dual RV670 based HD3870X2 from Jetway and HIS and we'll be comparing it with the original HIS HD3870 Turbo configured in CrossFire.

Nice review there.
You can notice these cards need a higher cpu speed/more cores.
I did a test with QX9650 at 3600mhz and got 19k 3DO6 wirh non oc on the cards.

19K is only due to Quad Core in the CPU tests, you know that right;)

45nm Core 2 Duo have improved single core performance too, not that much but it adds up.

it's the only 3D benchmark where those extra cores on his CPU will actually make a difference;) and in games there is none!

indeed, synthetic benchmarking and games are different!
