Radeon 7970 Maker Choices

So I have a Radeon 6770 and wanted to upgrade to play some games.

I found these cards all 7970 with same price.

xfx 7970 double dissipation black edition

They are same price of $340 but I am looking for only one. I don't do crossfire because its more complex.

 Cpu is 8350

 Ram is 8gb

 Mobo is Asus Sabretooth 990FX

 PSU is 600W

I use a single 21.5" Monitor at 1920 x 1080.

I've never heard of PowerCooler but between MSI and XFX they are the same really. Check which one has a better stock cooler for overclocking and a better warranty/customer service.

There is also PNY gtx 670 2gb for $200. Is that good?

I'd go for the XFX card. The other two look like they're going to be hot and loud.

That is a fantastic price - absolutely insane, actually. 

Where do you live? Can you give us some links for the prices of those GPU's?

Also, I was too late for the the price. But is the PNY gtx 670 is $320. and the XFX is $460 from some place. What should I do?
