6970 worth it? - Page 2

post #11 of 20
Are you looking to go eyfinity? if so then go for it, it will save you buying 2 nvidia cards to do surround. otherwise I'd go for a 570/580. the 570 gets higher frames in most games over the 6970 and is cheaper.

I only went for the 6970 because I eventually want 3 monitors and another 6970 and my mobo only supports crossfire.

To the OP, the 6950 and 6970 is 95%-98% identical in every way. A few have already mention the difference b/w the two cards, memory, memory timing, and voltage. That being said, unlocking a 6950 doesn't make it a 6970 but very close to it. An unlock/lock 6950 can do anything a 6970 can do if not better. The 6970 have better overclock potential due to the 8 pin and better memory w/ extra voltage. Though... you won't notice a difference b/w a 6950 @ 1000/1450 and a 6970 @1040/1500. Save $70 and get the 6950. Take 5 minutes to read the shader unlock guide and that'll increase your performance by 3%-5%+.

I just reread your post and I needed to point out a few things. You're referring to a 6970 bios. A 6950 flash to a 6970 was reported unstable and somewhat damage the card, less than a handful. A lot of 6950's owner are unlocking the shader w/ the original bios. This is safe and very stable. The process is also very easy. I advise you to unlock the shader only if you're going with a 6950.

This is false. The 8 pin PCIe plug is simply two more grounds. On most power supplies, they are wired directly to the other three grounds in the plug itself.

No difference whatsoever.

Also, I really have a hard time believing that it's different memory since both of my 6950 ( Asus 6970 oc bios ) will run at 1500 Mhz all day long.

Unless owners of actual 6970's are getting significantly higher memory oc's, then I believe it's the same memory.

YMMV, but I am very happy with 6950's!

Quick answer for OP:
GTX 570 or 6970 if you are not a risk taker.
6950 if you are a risk taker.

The OC capability of the 6950 and the 6970 are around the same, however, from the unlock you will see slightly less performance which will not hinder your game play significantly. Just remember that not all cards are created equal and there are a fair share of bad cards as well as holy amazing batman cards.

I bought the asus eah6970, I've not oc'd or stressed it yet, I'm still trying to get it to play nice with 3 monitor setup, idle temps are good though at 45°C.

There is a difference, it's called contact area. In DC electronics, the ground is more important than the positive. This is why in automotives the ground cable is often times a gauge or two larger than the positive. By adding the two extra grounds, more wattage can be reliably passed, since more metal is part of the circuit.

As for the memory on the cards, your cards may run the increased speed constantly, whereas others don't. Perhaps Asus did put better chips on the cards, or you happened to get two good ones. In pictures I've seen of both PCBs, the 6950 has lower spec'd RAM, the 6970 has higher spec'd, and does not run as close to the spec'd limit as the 6950.

All of these arguments boil down to nothing in the end. It's a forum, someone is asking for opinions, and we're gladly sharing them. Sometimes they're mixed with facts to help things along.

My concluding statement is this: if the OP thinks the 6970 is worth the price premium, then they should get it. I have no complaints of my purchase, even if it's marginally better (or not...don't know yet). Or maybe the OP could wait a little longer until the 7 series hits relatively soon, making us all poor buggers.

I agree IF there are actually more ground WIRES. But, on my Corsair 850 the "extra" two grounds are literally wired directly to the other ground wires in the plug. The cable only has six from the power supply itself.

That is why I say there is no difference here.

The ram is really anybodies guess, but I really think if the 6970 ram was "better" then we would see people getting much higher clocks on 6970's than we are on the 6950's.

Your right about the OP though and it really is a crap shoot on the 6950 but most people have had really good luck with just a few cases where it didn't work out.

Flashing a video card isn't for everybody, so maybe for some the 6970 is worth the extra $70-100.....

The "extra" grounds are to enhance the connection, and lower the losses at the connector, although just making a jump from one connector to the next with the wire in it is far from what I'd call optimal, but it would still make a difference, albeit less of one than individual wires. Not all PSUs are wired in that manner, either. My Corsair HX1000 has individual wires to each plug. Same goes for the PC Power and Cooling in the spare box I'm currently typing on. Maybe Corsair skimped on the 850TX you have. I had and older one of those models once, and think it also jumped the grounds from one connector to the other (this is a stupid idea, by the way). Take it for what it's worth, but more connections, even over the same wire, does improve things.

True about unlocking...sometimes people are uncomfortable, and sometimes they're lazy.
