===What is too high?===
Generally if you're not within the range of similar meshes made by EA, then you should investigate ways to reduce the count. If your poly count is twice EA amounts, then that is high, but might be justifiable if the item has a lot of curves or extra details. Anything higher poly than that would have to be very exceptional.

You're taking the time to make a mesh; take time to know what is a 'normal' poly count and to use just enough mesh detail to get the effect you want and create more detail using your textures. The better your textures, the better the overall impression your mesh will make.

Always remember:
LOWER POLY = GOOD
