You can use slot 1 and 4 no problem. Once you get into gpuz, you will realize slot 4 runs at x16 lane speed and slot 1 is only at x8. This is be a use lane 1 is wired to the cpu and lane 4 is wired through a plx chip.
To achieve x16 on both cards, you will have to run them both through a plx chip. Lane 2 and lane 4. The biggest stipulation is that your bridge will set funny, although spaced properly to work.
