I'm about a minute away from clicking to order this Gigabyte EP45-UD3R motherboard off the Egg to go along with my GTX 260, and i was scanning some reviews and i saw one where someone said that the GTX 260/280 cards "can't" fit into the primary PCIe slot due to the locking mechanism blocking the card itself. Can anyone please elaborate on whether this is true or not. Surely its not, but i'd rather be sure. Thanks.
