This might seem like a stupid question, but I just ordered a AGP Sapphire x800gto from newegg, retail: http://www.newegg.com/Product/Product.asp?Item=N82E16814102609. I have done a lot of searching around about this card, and I have found that some of them can be unlocked, and I have also found that there are several differences between pictures of the sapphire x800gto. For example, there is an OEM version of the same card of newegg (http://www.newegg.com/Product/Product.asp?Item=N82E16814102608) with a different model number (no L) and different picture (look at the top left of the card in the two pictures, there are missing diodes). I have also found there are red versions and blue versions. Are there any real differences in these chips?
