Can't decide between sapphire 7970 OC and msi lightning 7970 - Page 2

post #11 of 18
I had a sapphire 6950 and one of the fans went out. Reading on the forums and other various websites, it looks like its a common problem with sapphire custom fans. Last sapphire card i'll ever buy.

I've had 3 Sapphire cards, a 2600XT lol, 6950 Dual Fan and now a 7970 OC/Dual Fan. No problem with any of them, although I wish mine did OC a little better not that my OC is terrible but it's ASIC is 64% just an FYI what you can expect out of a low ASIC card I suppose.

I freakin' wish those lightnings could come back into stock. Sorry if slightly OT but does anyone have any idea when Newegg is due to restock? The wait is starting to get to me.

Lightning version is very different layout+component with others overclocked card. It has more PWM and different mosfet (copper mosfet) so it is targeting for high overclocking smile.gif
And so I choose MSI R7970 Lightning thumb.gif

Hi everyone, OP here. Just thought I'd bump this with an update. Ended up going with the Sapphire, and am glad I did. This thing overclocks like crazy! Using the 2nd bios the default voltage is 1170 mV. So far I've bumped clocks up to 1200/1700 totally stable with no voltage changes! And I haven't even tested yet to see how far I can push it. No coil whine or black screen issues either. Very happy with my decision

That is the most restrictive block you could choose though so I would have to thumbs down on that block.

I have the sapphire 7970 OC and it has been flawless and stupidly easy to install. No problems, but I haven't gotten around to overclocking yet.. It maxes all the games I have with ease... so no point yet, until I get a 120hz monitor..
