Planning on building a computer with these parts, if I buy a better graphics card will it run?

Intel Core i5-4670K CPU: http://goo.gl/HuwiVx

Cooler Master Hyper 212 EVO CPU Cooler: http://goo.gl/PbyUaz

MSI Z87-G43 Motherboard: http://goo.gl/qKuPUQ

Sapphire Radeon HD 7950 Graphics Card: http://goo.gl/wvxXci

8GB Corsair Vengeance DDR3 RAM: http://goo.gl/ozOZbZ

120GB Samsung 840 EVO SSD: http://goo.gl/cQcfco

1TB Western Digital Caviar Black Hard Drive: http://goo.gl/sHQiQm

600W Corsair CX600 PSU: http://goo.gl/UqiqRY

Corsair 200R Case: http://goo.gl/o7uoHK

Now I was thinking instead of getting the Sapphire Radeon HD 7950, I would look into getting a geforce 780. What is required to make sure this will run?

Fine build!! 780 could run on this!!! Maybe get a 650 watts for safety.

Drop down to a WD Blue HDD, or Seagate Barracuda and put the money back into the build in the form of a better PSU. For those parts, the Corsair CX line isn't going to be your best option. Xfx, Seasonic, OCZ, Rosewill Hive series, and other Corsair non-cx and gs models would be great.

^Yea I was thinking I would get a cheaper sdd, I actually plan on just using my 1tb harddrive in the computer I'm using right. So that's another $100 off the purchase. Also if someone could tell me, if I have an activated Windows 7 on the computer I'm using at the moment, could I use it on my new computer with the same activation code?

If that's the case, then the Blacks are a good choice.

If you have a prebuilt Pc like an HP or Compaq or such, chances are you can't reuse your Win7 key. If it's a homebuilt pc, then you should be able to.
