Trying to make a handle I want to make a handle like the picture;



The highlighted one is made from a path and the one behind it is made with extruding etc. The one made with the path looks the best but I'm very new to blender and I want to make sure that my poly count isn't too high. 

I'm making an armoured vehicle and as you can imagine this is a tiny object compared to the vehicle. I can't make all the details with a lot of polys because that will kill the server that has to run the vehicle (or I think that's how it works?) 

Is there an actual disadvantage/impact to having a lot of polys when you make something for a videogame? How heavy is the path-handle on polys? All it shows are the verts I used to make the path, not the amount of faces etc it used to fill it up.
I would use the path; it probably won't be too hard on the game engine. The extruded one should also work, although I would make it out of simple rectangles to keep the poly count down, unless you need to see it up close.

That said, you probably don't even need a handle at all--you can just paint it into the texture on the side of the vehicle.
