good day every body ..

my rig ...

Fx 8350 OCD to 4.7 GHZ
8 gigs of Ram 1600 Mhz
1 X 7950 Sapphire OC Edition OCD To 1130 /1450
1X S27A950D 27 inch Full HD 3D monitor .
3 HDD's .
Hyper Evo 212 Turbo Push/Pull .


i already own this card .. sapphire 7950 OC edition .
http://www.sapphiretech.com/presentation/product/?cid=1...

i was thinking of buying a gtx 780 but its very pricey yet .. and selling my 7950 wont boost my cash enough to fund the gtx so i thought about cross firing another 7950 but in stores i dont seem to find the same model i own i can only find those 2 models ..

http://www.newegg.com/Product/Product.aspx?Item=N82E168...


http://www.sapphiretech.com/presentation/product/?cid=1...



can my card be crossfired hassle free with one of those ? my card is running at 900mhz and 1250 i understand i should over clock the other one to run at the same clock in order to crossfire .. am i right ?


my other concern is that will my psu cougar cmx 700W 80 bronze be able to run 2 7950 along with 3 HDD's, AMD 8350, 8 gigs of 1600MHZ ram, hyper 212 turbo dual fan push/pull ...
this is very confusing here in my local market all sellers guarateed that the psu is fully capable but ive been told here its not adequate ... !!! any ideas ?

im only running 1 27 inch Full HD monitor 1920X1080 samsung s27 950D

my last concern is about over all performance will i be sensing a real difference with cross firing while im only running one FHD monitor ?

Thanks ...

Note ive asked this question in the GPU section and i had no reply so i thought maybe some expert here can help me ..

Regards .

First off, I wouldn't crossfire due to two reasons:
1. AMD crossfire drivers are really bad. You'll notice a lot of micro-stuttering and it's just not worth the extra money.
2. That psu is low quality, I wouldn't put two cards powered by that thing.

Cougar makes some fine PSUs ....
http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

but most score in the 8.5 range .... nothing scary but not exacctly promising for huge overclocks. The CMX series in particular is known for poor voltage regulation at the higher ranges ... so if overclocking, Id be worried at loads above 500-550 watts.

As for the CF issues, I would not invest in CF at this time

ok so now Cross firing is a void ... my other concern .. can the 7950 handle another year with me before being in a serious need to upgrade ? actually im not a huge First person shooter person probably in the coming months the games ill be getting are AC black flag, watch dogs , Pes 2014 mostly the 3rd person titles ... i can handle tomb raider maxed very well barely the FPS falls every now and then even when im playing in SS 3d ... in 2d i get 79 FPS in its benchmark .. also im running remember me maxed .. max payne maxed , hit man maxed , devil may cry maxed .. nothing so far i cant run on its highest settings, off course first person shooters are out of the equation for me cos im not a fan ...
so taking into consideration this given ... is it better to stick with my 7950 for another year or perhaps untill the gtx 780 price falls down or is it better to trade it in now for a 7970 because thats what i can max afford now, gtx 780 is intensely expensive for my financial situation now adays ...
trading it in for a 7970 sapphire will cost me around 257$ difference.... my market is a little bit pricey than the US market..
the over all deal is worth it or its not recommended and i wont sense much difference and its better to retain my 7950 for some time and giving it a boosty upgrade at the end to the gtx 780 ?
gtx 780 in my market is worth 735$ for the galaxy model by now... the gigabyte and evga are a way more expensive ... thats a SCi-FI price for me and no way im paying it ....


im thinking out loudly what do you advice me fellow members ?

Stick with it. Upgrading to the 7970 is way not worth it.

Supposedly, release date is July 31st .... given all the hoopla on the issue, id expect any release to be trumpeted all over the place ..

current drivers are 13.4 5/29/2013
Beta drivers are 13.6 Beta 6/7/2013

so id say the fix isn't out yet

Im looking for some fixes myself regarding extended display issues on a job I need to finish at a power plant.

now im having a friend who is offering to take my 7950 and give me his sapphire 7970 Vapor X 6gb Edition and pay him around 200$ is it worth considering im only using one 1920X1080 montor ? im tempted cos this version is very expenisve in local market and the price he is offering me is almost a steal ... what do you advice me guys ?

That is a good deal, but it is overkill. On a single 1080p monitor, you won't notice the difference between a 7970 3gb vs 7970 6gb.
If you plan to upgrade to a triple monitor set-up or something, then its a good investment.
Otherwise, the performance increase you'll get on a single 1080p monitor isn't worth the money.

i understand but the deal is unbeatable 200-220$ difference + my card wont get me a new 7970 3gb in my market .. we are talking 6gb Toxic .. have i mentioned it is Toxic not even the normal 6gb vaporX it is the Toxic ... im so so so Tempted ... and at the same time i would be very future proof and just forget the GPU for much time to come ...

what do you think ?

Not sure what's so special about the toxic? Isn't the Vapor-X better?
Anyways, the vram definitely won't help when the 7970 gets old.
How much does a regular 7970 cost in your country? Without the 7950 trade-in.

the toxic is factory over clocked to much higher values than the normal 7970 ...i looked at some benchmarks and it differs than the normal one by at least 15-17 FPS if not more and from the normal 6gb within 10-12 FPS ..

New the vapor X 7970 3gb costs 500$ + 4 games the 6gb is 650$ + 4 games the Toxic is 750$ alone ... my card worth 250 used ...
do you suggest i keep my OCD 7950 for sometime then upgrade once and for all for the gtx 780 when it gets cheaper ? i seriously wish i can switch to nvidia its just that their cards are very expensive ... gtx 780 gigabyte is for 780$ in my country .
what about the gtx 770 is it any better than my card ? here the GTX 770 OC 3X 2GB is for 500$
upgrading from 3gb 384bit to 2gb 256 bit is even an upgrade ?
im very confused i dont know if i just trade in my card now for the 7970 or the gtx 770 or just wait and save for the gtx 780 .. im just afraid my card looses its value and dont get me any money later when i want to sell it ...

Is there even any reason why you want to upgrade? Is the card not strong enough for your games, or do you just want to upgrade so the 7950 won't lose its value?
The 7950 and 7970 will lose their value at the same time, when AMD comes out with their new 9000 gpu series. They are rumored to be released in October this year, and when they are then the 7000 series will lose value while the GTX 700 series will probably go down in price.
I would say keep the 7950 because its still a strong card nonetheless.

so far there is nothing i cant run maxed as long as turning of MSAA and with descent frame rates .. max payne 3 , tomb raider , devil may cry , alan wake , remember me .. and mostly in the future releases i would be purchasing watch dogs and AC Black Flag ..mostly third person action/adventure games ... im not even a GTA Fan but considering im not into first person shooters so im not in to the hassle of battle field 3 and metro 2033 benchmarks etc since i have heard those games needs sci-fi cards to run them ...
i even Over clock my card to 1130 and 1450 MHZ which boost Frame rates hugely and if i let my mind speak their aint a single reason for me that makes me strive to upgrade now its just im seriously paranoid about the future and i really mean it im sick and im under treatment even when i purchase something i buy 2 of any thing due to the fear from the future ...
so the main reasons i want to upgrade now is the fear that my card dont get me any value later and the fear of Not being future proofed ...

thats it ... and thats why im taking advices here from experts who knows better than me ...

Not worth it. No gpu is "future-proof".
My advice is to wait until your gpu is actually too weak to handle games before buying a new one.

ill stick with your advice and later ill try with ebay and see if i can snatch a used 7950 by a good price they are falling down and i think i can snipe a good deal few months later and cross fire only if the well anticipated ATI driver at the End of july will seriously end the Cross firing mass of problems ..after upgrading to 8350 i still have my old X6 1100 T which can fund me the other card later but do you suggest by this time i upgrade my psu correct ? i really dont know this psu issue is very confusing retailers here are granting me that my psu is very powerful but ive had here numerous advices from experts that its a weak PSu and wont handle more than 550 Watts .. i dont know which road to follow ..
also another cross firing question .. when you cross fire does that mean your gpu is really running at the full power of 2 cards ? which means in 2 X 7950 = 6 Gigs of Vram and 512 bit ? in brief every thing is doubled ? am i correct ?

what about my PSU hec cougar 700 W is it efficient or shall i trade it in by this one
-SeaSonic M12II Bronze 850W
or
-CORSAIR CX750M 750w 80 PLUS

if those cant handle i can push my limits to this one ..
-Seasonic X Series 760W 80 PLUS GOLD

thats my max ...
