Which 6970 for Crossfire?

post #1 of 16
Thread Starter 
Hey All I currently have a Sapphire 6970 with an Arctic Cooling Accelero Xtreme. I can max the sliders in Afterburner no problem (950/1450). This setup works great but between the card/cooler/ and ordering the heatsinks for the card it was about $500. For the second card I'd like to save a little $$, plus the trouble of installing the cooler, and most importantly waiting for the heatsinks to come in (you have to order them directly from Arctic Cooling, which ships from China.) I'm looking at the following two cards which should run cooler, and be able to max the sliders in Afterburner as well. I'm just unsure which is a better bet/company. PowerColor or MSI?

MSI R6970 Lightning

or

PowerColor AX6970


Also, with my current setup my card never exceeds 45C, and is dead silent. Can anyone comment on temps/noise for these two cards? And as always, if there is a better suggestion than what's listed let me know! (Even if the ultimate best it to just duplicate my current setup)

Thanks!

looks like they both should work fine for you. The MSI is already at 940MHZ, so 10 will be very easy as most peoples temps seem to be in the 40s. Full disclosure though, I haven't used either. I am jealous though, as my 3 reference 6970s all run significantly hotter than what you have.

Ninja Edit: Looks like the powercolor is also 940. Overlooked at first. Flip a coin.

The lightning is a monster of a cooler/pcb design.

better power phasing, better cooling, easier OCing.. +1 for the lightning IMO

Can you space the cards on your mobo, or will they be stacked?

For the moment, Micro-Star Int'l stands as a better company than Powercolor; no one (important) foresees this fact changing in the next decade. Get the lightning. Get two more screens. Get gpu watercooling.

My lightning idles at 38 and after an hour of bad co its up to 70 c. Stock setting. When I o/c it to 1010/1500 its up in the mid 80's. I added 3 very good fans, 1 side intake, front intake (2 total ) and a top exhaust.

It's a great card.
