Matt, listen to Voidangel.
Stop wasting money AND time on this PC, it's not worth the frustration. You say your goal is to play 'Nowaday's games'? You're not going to achieve that with your current rig.
I suggest you return the videocard and demand a refund, they sold you a videocard not compatible with your system and therefore, they should take it back. You should look into buying a new machine if playing high-end games is what you want
By the way when you reset your BIOS 10 seconds should be long enough. Either shortciruit your CMOS or pry out your BIOS battery for 10 seconds.
The salesmen will try to sell you anything. When you ask if something's made of decent quality, he'll always tell you yes. Either because he needs to suck up to his boss or because he doesn't know enough about it. You see, anyone can sell a product but not everyone can tell you about the product.
Your mainboard is probably not compatible with your videocard. You might want to try contacting ASUS again. You may have sent in a faulty E-mail. Some companies require you to have a special word in the subject bar so it is not recognized as spam (Like AMD does..)
