Well, you can always exchange the modules. I joined the Kult forums and found out about the minimus system requirements:

Minimum system requirements:
- Pentium 600MHz or comparable
- 128 MB RAM internal memory
- 32 MB Graphic Card (GeForce2,
- Radeon or comparable)
- DX compatible sound card
- Direct X 8.1
- CD-ROM drive

I won't rely too much on this information, but Kult's graphics are equal if not supperiour to Beyond Divinity yet the minimum system requirements are lower. I might change my mind about Kult. Ah, I also read some more info on the editor:
It doesn't have a 3d program, you have to export your model from your own program, as well as the texture. Still I've become interested. Let's see how the project will turn out.
