Howdy!

Heres my situation. (please read, help, rep shall be given smile.gif)

I currently own a HIS HD 6950 2gb version card. I run a 3770k and msi mpower mobo. I have wanted to upgrade my graphics performance a bit recently so I went on ebay to look for other HD 6950 I could buy used to start a crossfire set up. I realy don't want to sell the card and would prefer to choose between the options below instead of just upgrading to a current gen card.

Prices range from $130-$170 for used. So my dilema......

I had originally a few months back thought I would just wait for the 8000 series AMD cards to come out soon, but now some pretty well substantiated rumors are saying that the 8000 series will not be out till very late 2013 or ealry 2014. example is in this weeks pcper podcast ( found it other places to though)

https://www.youtube.com/watch?v=_8czjBTGcMY

So what I want to know is:

1. What is the comparable performance of HD 6950 CF vs. 7000 series cards now ( I cant seem to find any good data on this on google or on OCN)

2. would it be worth the $170 to go for 6950 CF and be able to wait until both next gen card manufacturers have the new lines out ( i want to compare before buying new generations)

3. One that I'm eyeing closely now is a twin frozer 2 MSI 6950 to go with my HIS 6950. both are 2gb versions. What possible compatibility issues would I have going with different brands.

4. Is crossfire as easy as putting int he second card, changing a few catalyst settings and then good to go? (this is how i understand it works, but correct me if I'm wrong!)

THANKS in advance! and I promise REP+ to anyone with good insight or info on the matter! thumb.gif

Well, as far as I've read, 8000 series aren't to be released until next year, I don't think you can wait this long till you can upgrade.
Also, 6950's will be good enough in Crossfire if you're ok with the possible issues of multiple GPU solutions. I think they'll be on par with a single 7970. I'm not very experienced so you might want to wait for confirmation, but I try to help biggrin.gif.

yeah I have a few reservations about microstutter but I feel its something I probably won't notice it , and the drivers are matured enough now to where I feel I could find a set that would work well for the 6950 crossfire if I did it. Your opinion is kind of the way im leaning... so thanks for the help!!!

Anyone else?

can anyone confirm the comparible performance of a 6950 CF setup vs. ??? which 7000 series card

also microstutter opinions?

As far as microstuttering goes, it exists but it varies from one person to another, some people don't notice it at all, some people may notice and ignore, some people find it a major pain and unplayable.
If you don't get another 6950, what will be your budget? Personally, I think the 7950/670 are the lowest to go if you're not going with the 6950 Crossfire setup since the 6950's are good cards.

I real enjoy my crossfire setup. The newest CAT Beta driver have been great on my system.

Micro stuttering have not been in issue for me [BF3, Crysis 2, Metro 2033].

Borderlands 2 latency issue was fixed for me with CAT 13.2 Beta. Crysis 3 Beta
has some issue but it is beta and I have 1GB video ram limited (same Crytek Engine 3
as Crysis 2). CF is scaling better in Crysis 3 Beta with latest drivers.

RadeonPro is a great tool for ATI cards. Very useful for tweaking and I find it very useful to
customize CF for specific games.

If you setup can handle the extra heat from running two graphic cards and you really don't
want the hassle for selling current 6950 then CF is great solution. Not everybody will
have the same experience different configuration (hardware and software) but I find
people talk a lot about things they never used (no 1st hands on experience).

My 5850 CF setup get about GTX580 and HD 7950 (that was before CAT 12.11 boosted the 7series) maybe now HD 7870 level.
I would expect a CF6950 setup being at least GTX680/ HD7970 level.

If you don't like your CF 6950 setup you can always dump it on eBay. shouldn't loss much money (except listing fees and paypal).
But you will know that you don't like crossfire. learn something new. play around with hardware.

adding a 2nd gpu added 10c to my 1st video card. but ATI cards runs cool. did hurt my gpu overclocking. if I needed more power
I could disable the power saving features and turn up the volts.

Thanks for the great incite!!! Yeah i was having some issues that 13.2 seemed to fix on just my single 6950. I have my c70 case maxed out with cougar fans ( 4x120mm and 4 x 140mm) and I'm not that big a silence freak so I would not have an issue cranking them all up (usually run on full anyway) to exhaust some excess heat

So I'm leaning that way since the card I found seems to be pretty much as close to new condition as it can be (appears guy took good care of it)

Does anyone have a dissenting opinion just to play devils advocate?

its always better to go for a single GPU. CF scaling can work very well or poorly based on the game. CF issues like micro stuttering are well documented. generally it takes quite a bit of time to get stable CF driver support for the latest titles. power draw is lesser and you benefit from a cooler and quieter running setup.

you can ask in the HD 7900 users thread. many users have moved from HD 6950 CF to HD 7950 and have a much better, smoother and consistent gameplay experience. HD 7950 boost is 60 - 65% faster than HD 6950 at stock speeds. HD 7950 is 3 - 6% slower than HD 7970 at the same clocks. easily overclocks to 1100- 1150 mhz and matches HD 7970 Ghz perf. at those speeds its 80% or more faster than single HD 6950. in the latest DX11 titles like BF3, Farcry, crysis 3 a HD 7950(1.15 ghz) would be 2x or more faster than single HD 6950.

sell your HD 6950 for 130 bucks. throw in another 180 bucks and get a Sapphire HD 7950 boost. excellent dual x cooler. unlocked voltage. very positive user reviews.

raghu, with all due respect, in most of your posts that I've seen you say that " X " card easily overclocks to " X " clocks or so, that's not entirely true since he may end up with a card that doesn't overclock so well as u said in your last post. It's a silicon lottery, you can get a great overclocker or a bad overclocker.

accepted. i mention the stock performance first. i understand the silicon lottery. the average oc on the HD 7950 boost is 1100 mhz. that accounts for the best (1.2+ Ghz) and the worst clockers (max of 1 - 1.05 Ghz). so yes the user needs to keep his performance expectations around stock. the oc is the bonus. thumb.gif
