Yes, however, the main difference between cards manufactures is the way their coolers are design. Some companies may over clock their cards by a small percent and sell them at a greater cost.
Don't let that disturb you because the card is still the same card. (Maybe with or without other features such as V-out and others)
If you want to over clock it, you may need a good cooler, stock coolers are mainly not the best of choices but if you chose to buy from a company that already has a dissent cooler on their cards, you will only be more satisfied...with a bit less cash in your pocket. ;)
