GTX 560 Superclocked 2Gb vs Radeon 6870

[precursoris]

I'm putting together a computer build that will be used primarily for work and gaming. I've found some video cards that are ~$200. Which of these is the best:

-EVGA GeForce GTX 560 SuperClocked 2GB --> http://www.memoryexpress.com/Products/MX33579

-HIS Radeon HD 6870 IceQ X 1GB GDDR5 --> http://www.memoryexpress.com/Products/MX37061

-Gigabyte Radeon HD 6870 1GB GDDR5 --> http://www.memoryexpress.com/Products/MX35329

-XFX Radeon HD 6870 2GB GDDR5 --> http://www.memoryexpress.com/Products/MX35344



Here is the rest of the build:

When comparing some of the specs of the GTX 560 and one of the 6870, I noticed that the 560 had less Engine Clock and Memory Clock. Is this enough information to confirm that the 6870 is better?

Acording to this chart the two cards are on the same level and you will always find cards that are clocked differently. So being on the same level it comes down to a personal choice and it would be between the 560 and the XFX 6870. The components in your computer are fine and will go well with either card.
