Looks good, but save yourself $100 and get the 5850.
The difference is 5% at the same clock speeds. They can handle the 5870's BIOS, so you will not be vcore limited for sure.
1000 MHz core is almost guaranteed on models with voltage control. They are epic overclockers.
EDIT: This one looks to be the best deal on newegg.ca. http://www.newegg.ca/Product/Product...-500-_-Product
The cooler is made of awesome, and software voltage control is supported.
