No offense, but you clearly have no idea what you're talking about. The GPU in the Xbox 360 is very good all things considered, and all things includes the fact it was designed 7-8 years ago. At launch it had features high-end PC GPU's didn't even have yet. Considering it only has access to about 512MB of RAM at any given time, it's not surprising at all that highly detailed textures at high resolutions are problematic, but the same is true of the PS3. In the realm of consoles, the 360 is probably one of the most well engineered consoles to date.
