The 360 has it's own ATI GPU that was made specially for it, and as no benchmark program exists, it's hard to give a specific esitmation for the 360 GPU's power, but I think it's easy enough to say that games will try to run at 60FPS average on it and try to not drop below 30fps.
PC GPU's are far more powerful than anything in the consoles, but less optimised as PC games have to be made for a variety of components. The graphical gap is widening with the 57 and 5800 range from ATI and the released benchmarks of the gf100 from Nvidia. So in short PC GPUs are less harnessed than console GPU's, but make up for this, and easily surpass console GPUs, with sheer power.
In terms of what the GPU's do, they do the same things, which leads to my next point. Having looked at benchmarks for ME2, the card which gives an average of 60FPS in the game is the 8800GT - a card released in 2006 which was amazing for the time, but now is pretty dated. I basically used the PC GPU benchmarks as an indication of how graphically challenging ME2 is on full, and it isn't really. Because of this I suspected that ME2 wasn't going to be graphics king on the consoles. Unless a tech buff can tell me how this is wrong, I think it's a good way of checking how graphically demanding a game is going to be if it's multiplatform.
