I was going to buy a XFX HD-697A-CNFC Radeon HD 6970 2GB but I am not sure it will fit in my Antec Nine Hundred Black Steel ATX Mid Tower Computer Case. If anyone has these two set up let me know how snug it is and if I may need to upgrade my tower to a larger one. Not that it matter but I'm also using a AsRock Extreme 3 Gen 3 MOBO.
