Hello,
I am currently using CF5770's and am looking to upgrade to a single 6970,
though here is my question that I would like to figure out before I make my purchase


1. I am using a 650w psu and wonder if I can OC my 6970
2. Why does Serch always have to be on his stupid games and stupid computer? - Srotchette :love:  :bounce:  :o  :love:  :love:  :sleep:  :D 

More about : 5770cf 6970

Hello,
I am currently using CF5770's and am looking to upgrade to a single 6970,
though here is my question that I would like to figure out before I make my purchase


1. I am using a 650w psu and wonder if I can OC my 6970
2. What is the performance difference seeing that they are both equal to 2gb of memory
3. Does the 6970 have stable drivers
4. Is it worth it.

Current system
8gb RAM @1333mhz
Phenom ii x4 940 @ 3.3ghz
AMD 5770CF
mobo: Asus m4a89gtd pro/usb 3.0

Well, you don't actually have 2gb vRam. You have 1gb.CF and SLi do not add the RAM together. The hd6970 will be better, but not worth spending $300 on. Your cards will perform almost as well, and then you don't need to upgrade. The hd6970 should be stable. vRam isn't what makes up your performance either. If I were you, I wouldn't upgrade. Also, if you really have to have one, grab a hd6950 and flash it into a hd6970. Hope this helped! ;)

thank you,
and yea I'm aware that its clock speeds, shaders ect,
though i will sell both my 5770's hopefully for $200-$250
so i would be spending maybe $100ish additional.
still think a 6950 is the better buy?

You already have a pretty strong graphics set up as it will run most games on high on most resolutions - if you have money to burn the 6970 is a better choice but only if you have money to burn as the performance will likely be un-noticable for normal resolutions... (posting your resolution would help on a graphics card discussion).

The crossfire memory doesn't just add - it's been a while since i kept up and i'm a little rusty but i'm sure someone will explain.. in a nutshell the 2GB on one card is better..

650w for a single card is usually enough (i think the max usage on the 6970 is about 250W), should be fine if your already crossfired off it...

thank you too,
and my resolution running all games is 1920x1080

benchmarking and graphic mods on crysis :)

Yeah, they might sell for $120 - 150. I would stick with the hd 5770s. I can grab two hd 5770s on newegg for $190 at a bad price, so you won't get $200.

And yes, the hd6950 is the better buy.

Even if you can't unlock the 6950, it OC's like mad.

My 6950 can run 890/1385 on stock 6950 voltages. Not only that, but I was lucky and was able to unlock the shaders. It runs faster than a 6970 and runs cooler as it draws less power.

Finding an unlockable 6950 is quite hard now.

At your resolution, 5770x2 would do well. If you were at a higher resolution, I would recommend the 6970 or 6950.

Not if you buy a reference card.
