that card normally requires a 350w power supply but there are cases of it running on a 250w without problems. If you have a really good PSU then it may work but id guess no, it wouldn't
Any AGP graphics card (such as an NVIDIA GeForce 7600GS or an ATI Radeon HD 4760) will work. Depending on the power requirements of the card, you may need to upgrade your power supply.
Yes. See http://ati.amd.com/products/radeon8500/radeon8500/index.html
The NVidia is faster.
4870 by far.
23% of 8500= 23% * 8500= 0.23 * 8500= 1955
8.7% of 8500= 8.7% * 8500= 0.087 * 8500= 739.5
8500 metres = 8500/1 metres
40% of 8500 = 40% * 8500 = 0.4 * 8500 = 3400

20% of 8500 pounds= 20% * 8500= 0.2 * 8500= 1,700 pounds
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 240 volts / 8500 ohms = 28 milliamps
