Not really sure about your overall system but I can say that XFX is the way to go. They have a limited lifetime warranty. Used to work for a computer shop and out of all the video cards I had to send back, XFX were few and far between. Plus if you are going to be hammering you video card, why not get something with a decent warranty.

You can order Sapphire Radeon 8530's from newegg.ca ...  they seem to have just gotten more stock.

5770 only hash for 150mh/s to 240 mh/s i dont think its worth the money its really hard to get a stable high end over clock.
he means 5830 http://www.newegg.ca/Product/Product.aspx?Item=N82E16814102946 these can hash anywhere from 250 mh/s stock all the way upto 330 mh/s with proper cooling and overclocking
MSI 890FXA-GD70 is a great pick http://www.newegg.ca/Product/Product.aspx?Item=N82E16813130274 I've gotten over 5 of them so far.

I have a sapphire xtreme 5830 and I'm getting 300 Mhash with overclock. They are definitely the best bang for the buck. 5850's were great too but now they are sold out everywhere.
