Help with Sapphire decision

post #1 of 4
Thread Starter 
I recently purchased a Sapphire 7870, ignoring the warnings in the amazon comments, and what a shock. I had the same problem everyone else was having with the blackscreen. I returned the card to Amazon not wanting to deal with the RMA. So now I'm without beautiful discrete graphics. How is the quality of Sapphire 7950/7970 ? I've read the voltages are locked, how would that affect me, a small overclocker?

What are some voltage unlocked brands that are recommended?

the sapphire HD 7950 boost is one of the best cards. easily overclocks to 1.1 Ghz at stock voltage. user reviews are very positive.

HD 7950 boost was released in late August. core 850 Mhz with 925 mhz boost clocks. the boost will vary depending on TDP headroom. If you max out power to +20% the card will run at 925 mhz consistently without any clock throttling. at the same clocks HD 7950 is 3 - 6% slower than HD 7970. With a slight overclock on this card to 1.1 Ghz you will match HD 7970 Ghz performance.
