Different ID video's would not work.

Mod just removes chipset limitation, it's not miracle yet to make everything work with everything.
So only SLI-configs which can be done on "true" NVIDIA chipsets or X58 are possible yet.

will workout it this evening. Now I'm goint to bed, no sleep to 50+ hours.

1. I always preferd SLI over Xfire but I have a P5Q Deluxe cso i like how it Overclocks my CPU so i was wondering if the nv4_mini works on my board.
2. And if it does would i have to get an SLI bridge for my particular MoBo or Graphic Cards i have a xFx GTX 275 and a spare 9800 GT
1. Yes, it will work, no matter what motherboard. But you also need to edit DSDT tables.It's still necessary.
2. No, 275 + 9800GT don't work now.

Please, dear ALL, understand that different cards would not work, it's way much complex to make it working , than modding chipset limit things.

So only legit SLI configs are supported, 2-/3-/4- ways which are working on "official" SLI systems.
