To be honest.... I'd go with either of the following graphics cards :
Note: I know you're not from Canada, but with regards to pricing and other prices brought up... here's what I've come up with.
Gigabyte 3GB DDR5 W/ AMD Radeon HD 7950 Chipset ($489.99 CAD)

OR
MSI's 2GB DDR5 w/ Nvidia GTX 680 Chipset ($549.99 CAD)

Both of these cards will run any current generation game, and I'm willing to put money on it that they're going to be pretty solid cards and will be able to run even some next gen games. Happy shopping!
