The insane speed of GDDR5 makes up for the comparatively low memory bus (compared to GTX280). So, the 1GB version would be able to compete more effectively at very high resolutions or in games with very large textures etc, as I understand it. Also, I think Crossfire can benefit from both cards having more than 512MB of memory.
