Okay, of course meaning OEM as being a 3rd party manufacturer of Radeon 9700's I assume, and not as the common definition of OEM as meaning "less or no warranty, no box, no name, etc", like an OEM CD drive. Correct? I don't even think there are those kinds of cards out there...so I imagine it's safe enough to pick which manufacturer you prefer. I mean it's not like NVidia makes their own cards, just the chips...and nobody hesitated getting another card from another manufacturer then, right? At least I don't think they make their own cards???
Anyways, well there is no reason why not to go with a company that will give you a better HS/FAN or Memory Heat Sinks...games/software, etc. I don't think. Again, how about it, anyone to watch out for that stands above the rest, or one to NOT get?
I haven't seen the Gigabyte anywhere for sale in Canada, just original ATI cards, with the exception of one, a Powercolor (I think it was called), and it had silver Heat Sinks on the memory...looked pretty sharp, other than the silly box it came in.
