Would a 7950 suffice for that task or would a 7970 be necessary? I ask because there is about a $100 difference between the two and I am just trying to justify the extra cost if I were to select the 7970.

You wouldn't really notice the difference if you're overclocking, if you're running stock the difference might be worth $100. You'd be better off putting $100 into a second card later or into something else like an SSD.

I'd suggest to get a nice 7950 and save the rest of the money. thumb.gif

I just switched over to trixx... how do I raise the memory voltage? Also, am I able to still use MSI AB to monitor stuff?

Unlike the 6950/6970 comparison, the 7950 is actually quite a bit slower than the 7970. I would say the 7970 is worth the price easily. I've been able to get my hands on 7970s for 299 within the past 2 weeks. I own 7 of them, and I'd say they're easily worth the price increase.

That's the price I paid for my 7950!!!! redface.gif
From what I've seen/heard a 7970 is only 3-5% better clock for clock which isn't a lot and most people won't see the difference unless it's an actual benchmark.. It's better value for money.

clock for clock HD 7950 is 3 - 5% slower than HD 7970. the extra shaders don't make a huge difference . bruennis has showed that with his Gigabyte HD 7950 which is one of the best overclockers on ocn and kept up pretty well with HD 7970s at 1300 Mhz. If you are overclocking HD 7950 cards are the best value for your money.

MY OC'd Gigabyte WF3 7950 beats the snot out of a stock 7970. There is not much difference between the two. And I think Gigabyte by far is the best for cooling purposes. See my post on page 1767.

http://www.anandtech.com/bench/Product/645?vs=618

There is a 15% difference in clock speed in those benches. There is NOT however a 15% difference in performance. 3 - 5% clock for clock is an understatement. In fact, 5% is the minimum. In some games, the performance is more like 15% clock for clock. It all depends on the game.

This is a direct quote from the Anandtech review of the Factory OC'd 7950 vs the 7970 stock.

"Even though the 7950 is well behind the 7970—to the tune of 24%—it’s still 33% ahead of the GTX 580 and the lead only grows from there. Meanwhile the XFX and Sapphire cards can catch up to the 7970 somewhat, but as this is truly a shader-bound test, you can’t make up for the lack of shaders units on the 7950."

This was in regards to the SmallLux Bench. It depends on which game you're running. Keep in mind that the 7950 was OC'd vs the 7970 and was STILL behind by 24% in the shader bench. The 7950 simply lacks shaders, and in some games it DOES matter. Some games are NOT shader limited and therefore you can note a 5% difference, but you cannot make a blanket statement that there is only a 5% difference. In NO way is the 7970 vs 7950 like the 6950 vs 6970 battle of yesteryear.

I'm choosing between the gigabyte 7970 overclocked and Ghz edition. Would both OC to around the same level?

There is a 15% difference in clock speed in those benches. There is NOT however a 15% difference in performance. 3 - 5% clock for clock is an understatement. In fact, 5% is the minimum. In some games, the performance is more like 15% clock for clock. It all depends on the game.
This is a direct quote from the Anandtech review of the Factory OC'd 7950 vs the 7970 stock.
"Even though the 7950 is well behind the 7970—to the tune of 24%—it’s still 33% ahead of the GTX 580 and the lead only grows from there. Meanwhile the XFX and Sapphire cards can catch up to the 7970 somewhat, but as this is truly a shader-bound test, you can’t make up for the lack of shaders units on the 7950."
This was in regards to the SmallLux Bench. It depends on which game you're running. Keep in mind that the 7950 was OC'd vs the 7970 and was STILL behind by 24% in the shader bench. The 7950 simply lacks shaders, and in some games it DOES matter. Some games are NOT shader limited and therefore you can note a 5% difference, but you cannot make a blanket statement that there is only a 5% difference. In NO way is the 7970 vs 7950 like the 6950 vs 6970 battle of yesteryear.
No, it's really ~4%.

plus, 7950 with Boost is slower than 7950@900Mhz. It's about the same performance as 7950@860Mhz
