If the card is broken, then "nothing" will make it work. To be able to use the card, you will need drivers for it.
A computer
No
If you have a graphics card that supports HDMI you can of course connect the PS3 to that card. Will it work at all? most likely not. why not
No it will not.
No. However they do help it other out. If for instance you were playing Half Life 2 and you knocked an object over. Instead of the graphics card having to work out the image of the object falling over and the physics of how it would fall, the physics card shares the work (the physics bit) allowing you graphics card to concentrate on graphics. The idea is that the combination of the two will speed your your system/make gameplay smoother
Any PCI-E graphics card will work.

Yes, you have a very nice graphics card.
