I need help choosing either a GIGABYTE GV-R797OC-3GD or a SAPPHIRE 100351SR.

Both are over clocked cards, and relatively same price, I was wondering which one you would get and why?

However, the GIGABYTE says it has memory clock of 5500MHz. and the SAPPHIRE says it has a memory clock of 1425MHz(5.7Gbps) / 1450MHz(5.8Gbps). Can someone please explain to me the difference? And or if they are both the same? Because all other specs are similar or same.

  1. As for the memory speeds I am not sure, but in just about anything AMD Sapphire is the way to go.
  2. I've never had a GIGABYTE card personally, but i can vouch for the quality of Sapphire cards
  3. ASUS! ASUS! ASUS! if not then sapphire :( ASUS! ASUS! :)
    I love my ASUS 7970 DC2, and the giant 3-slot cooler helps OCs alot.
  4. I use sapphire as they are NOT voltage locked. No worries
  5. For AMD GPU's Sapphire is the ONLY manufacture to get from. Have been using Sapphire cards for years had have not had one fail yet. In fact they are all still running in rigs to this day and that is as far back as the 3850(AGP).
  6. I wouldnt go as far as only, but it is the first choice.
  7. Its going to come down to what the newegg page says about the memory clock speeds. if the Gigabyte runs 5500MHZ and the Sapphire only runs 1425MHz(5.7Gbps) then Ill go with the Gigabyte, unless its the same thing, then ill go with the Sapphire, Because the Sapphire product page says it has 5700MHZ memory clock. So I dont even know how to determine this.

    I think its newegg making it seem wrong. They both run at the same speeds, the sapphire is actually faster. I would go off of the gigabyte speed and then with the sapphire its the (5.7Gbps) Which should equate to 5700MHz which is faster than that of the gigabyte.

    Thats exactly what im thinking, but still wondering where they pulled 1425MHz out of.
  10. I have been wondering that too, as the sapphire 7950 I am looking at has the same thing.

    You have to use GPUTweak 2.2.1.4 to unlock voltages on ASUS 7970s... ASUS didnt do a hardware lock.
