Ah, so the 80" is desk size rather than room size?
Assuming yes, and that you have space both sides of the desk, then you should be fine. Horizontal monitor dimensions are usually a little less than the marketing dimension—but of course that depends on what monitors you have.
34 + 27 +27 = 88;
Knock off say 3" for horizontal = 85;
Each 27" can overhang edge of desk by ~6", =73".
i want to have my pc on the desk aswell
Obviously depends on how wide it is.
If you give us any info at all re what monitors and PC, we can probably avoid guessing and assuming.
