Open Mesh vs closed mesh

Ok this is a silly question , im working on a game that uses 3D models but has 2D game play.
the camra angle never sees the backs of the models, so i have been deleteing the back areas of the models to reduce polygon count, i was wondering would this slow the engine down haveing non closed meshes?

hnmm oh ya another question.
also i found out later on after ive done a great deal of models without backsides the engine uses back face culling , would backface culling be more efficient than deleteing the back areas of meshes?
id like to see this game run on slower machigns above 60 FPS, it runs on mine perfectly. but on slower machigns it seems to lag a bit. ive only got about 16,000 verts and 9,000 polys if i re add teh back side polys the verts will rise just a bit , but the poly count will rise quite a bit. so they will become just about even count wise,

anyways im more intrested in finding the answer for the first question , but both would be nice

Having less triangles is always more efficient, so you should have it with the holes. Due to the backface culling the difference won't be that big, but there will be a difference.
