OpenGL performance when rendering a "virtual gallery" (textures)

Question

I have a significant (120-240) number of 640x480 images that will display as textured flat surfaces (4 vertex polygons) in a three-dimensional environment. About 30-50% of them will be visible in this frame. It is possible for them to crossover. Nothing else will be present in the environment.

The question is whether the modern and / or multi-year (say, Radeon 9550) will cope with this, and what frame rate can I expect? I aimed at 20FPS, but 30-40 would be nice. Will a resolution change to 320x240 be more likely?

I have no previous experience with 3D graphics on modern GPUs, and, unfortunately, I have to make a design choice. I do not want to waste time on something that did not work :-)
