Fastest GPU Out Of These?

[thomasd221]

Hello there, I am selling my two Sapphire Radeon 7770's on eBay here:

http://www.ebay.co.uk/itm/Sapphire-Radeon-HD7770-OC-Edi...

With the money I get from these, I am gonna upgrade my PC to either a 5970, 6970 or 7950. I've heard the 5970 is an absolute beast because it has dual GPU's, but i've also heard that it runs hot and is very power hungry.

I've heard the 6970 is a good performer, but not worth the price?

And I've heard the 7950 is a good performer, very overclockable and very power efficient.

My Specs:

Gigabyte GA-970A-DS3
AMD Athlon II X4 640 (Will soon be an FX-6300)
8GB Kingston HyperX Blu @1333 (Should be 1600, but CPU limits it to 1333)
Either a 5970, 6970 or 7950
FSP Bluestorm II 530W (80plus certified)
Antec GX-700 Gaming Case
Windows 7 Ultimate 64
1x 750GB & 1x 500GB

So, which is better for my system? The 5970, 6970 or 7950?

Thank you for your time.

7950 for sure. It's the newest card of the 3, and if you decide to crossfire at some point the option is wide open since they are still on the shelves. 😉 You will need a new power supply if you decide to crossfire the 7950 though.

Thank you, I will probably get a MSI/XFX 7950. I heard the 5970 was faster?

No most of the time the 5970 is slower than the 7950. Especially at higher resolutions since it has a larger memory bus and amount on one GPU instead of being shared between two GPUs like the 5970 does. The only time it may be faster is when crossfire is working the way it should in certain titles only that do not use a lot of gpu ram.. Look at this review of the MSI TF3 7950 and you will see what I'm talking about. http://www.techpowerup.com/reviews/MSI/HD_7950_Twin_Frozr_III/13.html
