I tested 16x|8x vs 16x|4x in my 16x|8x|4x|8x mobo. The differences between running slots 1 and 3 vs 1 and 2 @ 1920x; 1FPS in the 20-40FPS range, 2FPS in the 40-50FPS range, 5FPS in the 70-80FPS range. So it should have a very small impact on your min FPS. You can decide if you think the hit is worth it. Keeping the cards separated will reduce both your idle and load temps as well as keep the fans from running medium high most of the time when gaming.
I got those numbers from; Heaven v2, Dragon Age, The Witcher, Age of Conan and Crysis.
