First off, I'd like to say hi to everyone as this is my first post on this forum. I have come here with a problem. I recently bought a 9600GT 512MB after my 7950GT 512MB burnt out. I sent the 7950GT back to eVGA for an RMA. Today, I received the card back from eVGA, but it wasn't a new 7950GT, it was a 8800GTS 640MB! Do I return my 9600GT for a full refund and install this 8800GTS, or do I leave my 9600GT in my computer and sell the 8800GTS on ebay? Please Help.
