So long as you know the risks with XFX, then whatever. smile.gif I have been hearing more and more lately that they're getting better with warranty.... but their BE cooler is absolutely horrible on the 7900's.

thats not true at all i have XFX7950 BE 900mhz one... and i manually overclock it after reading this to 1050core/1500mhz memory with stock voltages
and i adjusted the fan at 75% and temp were never more than 60C on 3dmark

What about your VRM temperatures though?

That's a 2% difference clock-for-clock.
HD 7950 is the beast of current generation GPUs. A good clocking HD 7950 will require good 670s/680s & HD7970s to keep up with it. AMD's decision to clock it really low at 800 MHz was a really stupid decision IMO because lots of people don't know the true potential of this card.

I'd like to see the 7950's scores in each of the tests in 3DMark11, but still. Clock for clock the 7950 is just absolutely insane for it's price bracket. And knowing that most 7950s can reach 7970 Ghz clock speeds out of the box on stock voltage is even more impressive.

We know you hate XFX, but it's about the silicon not the brand right? It doesn't matter what the damn brand is whether it's a base core edition or a 600 jobber lightning crapper, it's about the silicon lottery.

I am not a big fan of XFX. Their warranty is fine but they do silent revisions on cards.... which is annoying.

You know, they weren't the first ones who started revising the pcb right? Powercolor and MSI were first. Hell Powercolor even sells a 7970 with a freaking 7950 PCB for christs sake.

I'm considering a 7970. I want the reference cooler. Have there been any silent revisions on reference cooler cards? I was probably going with Asus, any reason to re-think?

How prevalent is coil whine in these cards?

the reference HD 7970 cards are good if you will stick to stock speeds or slight overclocking at stock voltage to 1 - 1.05 Ghz . the cooler can get loud with fan speeds above 50% and its not capable of cooling very high voltage overclocks above 1200 Mhz. but the ref cards are best option if you want to watercool. HD 7970 waterblocks are designed for the ref HD 7970 card.

I want the reference 'ducted blower' cooler because of my case layout. I though these cards were supposed to be very quiet. Can anyone comemnt on noise levels vs the GTX 580?
