Used 7870 vs Used 7970

post #1 of 30
Thread Starter 
Hey everyone, I'm in a kind of a predicament. I'm looking for a new card to run 24/7 on GPU-intensive work, such as folding at home.

I found a seller with a MSI 7970, but unfortunately he purchased it early from the looks of it, because it's this card: http://www.newegg.ca/Product/Product.aspx?Item=N82E16814127652 <-- From the reviews it looks like this card is super noisy, which is disappointing for me. I'd like the card to run relatively cool (70-75C max) and mildly-quiet (I currently have a 7850 at 65% fan speed running, it gets kind of noisy) Basically my noise limit is around 65-75% fan speed on most 7xxx/6xx cards, just so you can get an idea. He's asking $300 for this card.

However, this seller also has 2x MSI 7870's with Twin Frozr coolers. He's asking for $160 a piece. Unfortunately my motherboard only has 2 slots open for GPU's, and one of them is filled with a 7850 already.

So what do you think I should do? Purchase the 7970 and hope it isn't too loud compared to my 7850, purchase a single 7870, or don't purchase either of them, and wait it out until I see a similar card on the used market?

Why use AMD for a folding rig? Doesn't Nvidia have the edge in folding right now?

Nope AMD is on top again. And it will mainly be used for other things that are GPU intensive like F@H. In the program I use, AMD GPU's will always be on top.

The 7970 is going to be the most powerful card, very noticeable in comparison to the 7850/7870. Keep the fans low, and don't push an OC, and it should be quiet enough.

2 7870s, wait for driver fix, sell the 7850. Will be the 2nd cheapest option (other than 7850/7870 cfx) with the most performance. As long as you have enough space and power, you should be fine.

Well after looking over my options I've kind of decided that I'm going to pass up on both cards. The 7970 would be noisy, and a 3rd party cooler would cost even more, plus they apparently don't really cool the VRMs at all.

The 7870 would be nice, but I'm just not sure how it would perform with a 7850, and how well crossfire works and so on. Ill sleep on it, but I'd appreciate other replies with your thoughts.

You can't run a 7850 and 7870 together anyway.
I would go with the 7970, it's a great card. You will not regret it, it can get loud sometimes! But it's worth it for performance.

actually you can run a 7850 and 7870 in crossfire they're both compatible with one another, the 7870 will drop down to 7850 performance though.

QFT, only if its a 7870 XT tahiti LE IIRC you cant crossfire with a standard 7850/70 due to different GPU's

still i would go with the 7970..
