mostly sapphire and several his, all with 2250 memory
i got one xfx and it died in several days with stock rom
btw you can also look at your asic quality, if it is low, then high power rom will work better and vice versa
Yeah I've seen success with MSI on another forum. Which ASIC is considered good and which is considered bad. My XFX is running with SAMSUNG GDDR5 memory per GPU-Z.
