I would susgest to wait a little longer untill US Black Friday sales is on (Nov 25), I suppose you can get any Major brand nVidia GTX550Ti 1GB DDR5 or GTX460 768mb DDR5 at around US$80 after rebate. However a nice 80 Plus certified 500W PSU is a must for these cards.

If you must get a bang for the bucks video card right away, consider XFX nVidia GT240 512 MB DDR3 at CAN$20 after rebate, I suppose this is the best card you can find at this price for now. You don't even need to upgrade your PSU as it is an ultra low power consumption card.
