Sorry, this is probably a n00b question, but I have been browsing the Hardware forum looking for good options for some graphics cards I can put in a 2-3 GPU rig and I have seen a lot of posts related to Reference vs OEM Design cards.

My question, is that from searching eBay and other sites, how can I tell just from the photo which type of card it is? Is it as simple that reference cards have fans out the back??

Thanks in advance.

Look at the official product photo on amd.com or nvidia.com. If the card you want to buy doesn't look like that photo, then it's an OEM design card.
