^So pano setup nyan? NVidia setup para bang yung secondary PhysX?
Nope as in secondary card gaya ng sabi ni Dyaems
pwede sila crossfire, kaso kung di ako nagkakamali, yung lower clock ang gagamitin ng parehong video card? kung si MSI ay 30mhz less core clock kay ASUS, mag downclock din si ASUS ng 30mhz.
Yup, AMD allows Crossfire of 2 different AMD video cards from the same family. e.g. 6770+6750
Sa case ng setup ko, I am using a board & vc with Lucid Hydra chips. This just allows me to combine 2 different video cards to make them coexist in the same system. If I turn it off, both cards will run independently of each other. If I turn it on, the Lucid chip acts as a load balancer balancing the workload on each video card.
Although many dis this technology, few people have noticed that Lucid Hydra works best when using a combination of 2 AMD (different or similar) video cards
. Its performance is mediocre when using 2 Nvidia (different or similar) video cards
and a little bit wanting when combining AMD & Nvidia video cards
Di ko alam kung bakit ganun pero theory ko eh since AMD was designed to allow Crossfire of different video cards, malamang mas adaptable yung mga vc nila as compared to Nvidia which requires 2 identical video cards to SLI.
