Which brand should i get for radeon HD 6790?

get the XFX one.

eVGA for nVidia and XFX for ATI.

thanks and it should be a good card with this build right:
AMD Phenom X4 955
4GB DDR3 Ram
with a 21' screen resolution 1680x1050
Corsair GS600w

would it be okay to use on a 32' full 1080p LCD Tv? as a once in a while screen...

Yea it should run fine with that PC.

Really up to you on choice.The HIS and XFX cards come with DIRT 3 which is always a good bonus.Also I've seen that the HIS IceQ X Turbo's heatsinks is acutally quite good.
So that might be something to think about also.

I don't recommend the 6790. The 6850 is close to the same price point, it runs cooler and better than the 6790. The 6790 was meant to fit the gap between 6850 and 6770 but it's crap  .

XFX 6850 $140 after MIR

Power Cooler $147.5 after MIR and Shipping

Yes I would have to agree with wintermint the 6850 would be a much better choice.The 6790 use's 20watts more but performs worse.

Yea, I was tied between the 6790 and the 6850 but i think ill save some money to get the 6850 instead. Again tho, what brand? XFX is preferred but i get confused when someone recommends another brand like the Power Cooler wintermint suggested.

I believe wintermint was suggesting those cards because they are the cheapest 6850's.

Actually I just stumbled across a Open Box MSI Cyclone 6850.
