GTX 560 SLI vs 6950 CF Unlocked

post #1 of 13
Thread Starter 
Hey guys, just a quick question from a noob here. Which would give me better performance, the SOC edition of Gigabyte's GTX 560 ti (from what I heard, the best 560) or 6950's in CF unlocked to 6970's?

Also, is there any danger in unlocking your 6950? Could it ruin your video card?

I'll be running one 27" monitor at 1920x1080 if it helps.

Heres my specs:

Asus P8P67 Pro
Core i5 2500k
Noctua NH-D14 with extra fan
Corsair AX850
HAF 932 Advanced
G.SKILL Ripjaws X Series 8GB DDR3 1600
SAMSUNG Spinpoint F3 1TB
GTX 560 SLI or 6950 CF

Thanks for help in advanced!

In this fight, unlocked 6950s would be superior. But, you should add into consideration 480s, they're equal to 6970s but can be overclocked like crazy, especially if you add aftermarket cooling. With sales and such, 480s can be had for as little as $220 each (Fry's $300 + $80 MIR)

So GTX 480 SLI > 560 SLI/6950 CF unlocked?

Even 6950 will give You better performance than GTX 560Ti SOC. I don't even count unlocked 6950 to 6970 because it will destroy GTX 560Ti SOC o.O. I have both brands and I think 6950 is the best bang for buck right now, with awesome performance and good price. And i don't think You could damage Your card as long as You have dual BIOS switch on 6950.

Significantly better. It's also significantly hotter though, so you might consider looking at adding an aftermarket cooler, but it'd end up around the same price as the 6950s, but with a lot more performance. Your PSU is fine for it as well. The AX850 is an amazing PSU.

6950 cf for sure, double the ram, and unlock, wished i bought the 6950 2 g instead of the 560 ti, but at the time i bought the 560 ti, the 6900 s driver wasnt really good, now they are really good.

Here are a few of my own personal GTX 560 SLI benchmarks.

GTX 560 Benchies

I obviously can't speak on the 6950 CF, but it seems that driver issues still plague the ATI side. I had to do quite a bit of tweaking to get my 5770 Crossfire setup working correctly, and judging by the amount of posts I see asking for Crossfire help recently, this has not changed much.

The bottom line is *BOTH* setups will pretty much destroy any game out there, so I guess just flip a coin!

One more quick question real quick. I was just watching this video on how to flash the bios of 6950


and the highest rated comment is pretty scary
Quote:
PLEASE READ THIS ADVISE IF YOU ARE GOING TO FOLLOW THE VIDEO:

be sure to ONLY UNLOCK YOUR STREAM PROCESSORS, if you change the voltage or anything from the RAM, you will start getting artifacts in a round a week

please thumbs up this comment so everyone sees
Is this true?
And if it is, if I were to do what the guy did in the video would I get artifacts? I didn't see him change the voltage but I'm really dumb when it comes to this. Grr I probably sound incredibly stupid right now, sorry for all the n00b questions >.>

480 SLI does provide a great amount of performance.
But be aware!
They also have a very high power consumption rate which as a matter of fact creates great heat development.

So you should consider including the price of an aftermarket cooler into the original price of the 480.

Also due to the extreme heat problem stability issues follow and inhibit most people of achieving the max overclock.

The only circumstance a 480 should be considered is if they were to be watercooled

6950 CF vs 560 TI SLI is a clear win for the 6950 CF we don´t have to talk here

As in terms of the unlock:
There are two types of 6950 unlocks:

Type 1 unlock: Shader increase to 1536 units (same as the 6970)
Type 2 unlock: Complete BIOS flash to a 6970

The type 1 unlock is almost risk free and can be achieved with almost all the 6950´s.
The type 2 unlock on the other hand is a bit more risky because due to the full 6970 BIOS flash also the timings of the 6970 and other settings which are much lower or different will be applied.
To some cards that ultimately can lead to card failure.
But be advised that the Type 2 unlock only yields about 1-3% performance increas.
Wheter the Type 1 unlock + stock 6970 clocks have shown to yield the exact same amount of performance a normal 6970 would achieve
Maximize your screen to fully be able to watch the picture


I would also like to refer you to my thread in which similar questions and all advantages/features of the 6950 including all designs etc etc should be displayed and answered
I apologize for the multiple trolls and idiots that have pretty much destroyed the thread but it should still be able to help you pretty good anyways
