Makes sense, but does it.
So basically if i had three or even four 5770 in crossfire it will still only based it's score on the primary graphics adapter.
but if i have two SSD in raid the primary hard drive score will go up but not for video cards in SLI or Crossfire wonder why that is.
I thought SLI or Crossfire was two or more video cards acting as one like raid for HD's
That shouldn't be the case, according to a quick Google search, the WEI system was updated to take SLI and CrossFire into account from Windows 7 build 7201 (one of the betas), RTM is build 7600.
WEI will be higher if you're running SLI or CrossFire. I had a 8800GTS 320mb card previously, and when I added a second in SLI my WEI scores did definitely go up for graphics and gaming graphics.
