Whether you are a Sony fanboy or neutral. The XBox 360 has the best graphics card despite the XBox 360 with its well known hardware problems. The graphics card for the XBox 360 is 512 MB, thats is as good as most PC graphic cards.

False. The 360 shares 512MB of RAM with it's CPU and GPU. The PS3 has a total of 512MB of RAM. 256MB dedicated to one, and 256MB dedicated to the other. Yeah, of course you can use all 512MB for the GPU on the 360...but where does the processing for the actual game come then, huh? You can't dedicate 512 to graphics on the 360 and have a functioning game.

Yes, with regard to RAM size a similar situation is the case for the PS3. On the PS3 the CPU needs system RAM as well. However the GPU has fast access to the XDR Ram as well, so this RAM can be used if needed. The Cell has slow access to the graphics RAM, but this doesn't make much sense for use in games as the XDR Ram is faster combined with low latencies which is important to CPUs, especially for a CPU like the Cell. (also the Cell isn't really in need of more RAM, the huge bandwidth is far more important by an order of magnitude)
