I was having a disscution with a friend yesterday, about Physx. And i came with some doubs too... i know i can run Physx on the 8300 IGP, ive already tested, but it lacks the power to do any good. My friend ask me what happen if i plug a PCI or PCI-E 1x nvidia 8x/9x card... surely Physx can run on it too... but... i wonder if, what happen, if i plug something like, a 9400GT PCI? those exist, Sparkle has of those. I wonder if... W/O a Radeon on the PCI-E 16x slot: 1) Hybrid SLI can be enabled on IGP/PCI Card? 2) Its possible to run Physx on a Hybrid SLI like that? With a Radeon on the PCI-E 16x slot: 3) Hybrid SLI can be enabled on IGP/PCI Card, even if a Radeon on the primary PCI-e 16x? 4) Its possible to run Physx on a Hybrid SLI like that? (Using Win7) 5) Maybe Hybrid SLI cant be enable on normal PCI, what about PCI-E 1x on both cases? BTW 1, just remember motherboard support Discrete card and IGP. BTW 2, i not thinking about buying a PCI/PCI-E 1 nvidia card to do this, Physx dont worth it, and PCI/PCI-E 1x cards are way too expensive here, i just whant to know.
