The gang at has a review up of the MSI motherboard powered by the Intel Edition of the nForce4 SLI chipset. 
The SLI performance problem that the likes of Dell would inevitably gloss over, but has been graphically (pun intended) shown on the previous few pages is squarely down to Pentium 4s’ relatively weak gaming performance that’s exhibited at lower resolutions and/or with games that rely on masses of subsystem grunt. With respect to SLI’d gaming performance even dropping in an Extreme Edition would do little to help bridge the gap between equivalent Intel and AMD CPUs. That’s why, purely objectively, SLI doesn’t make the greatest deal of sense for LGA775.
