Hey all ..

I was just thinking of upgrading my PC for Battlefield 3. ( new gpu's)
as they say in the preview you will need get a 6990 or a gtx590 for good frame rates to have. ( ultra + AAx )

these are my current specs of my PC.

CPU: AMD Phenom X4 965 Black Edition@3.4Ghz

GPU: Sapphire 6870 1GB ( its bad ) it isl DX11 Un-friendly / AAX

MOTHERBOAR GA-MA790X-UD3P (six core supported and CrossfireX)

RAM: 4GB DRR2 ' i know ddr2 but it doesnt affect the fps.

1TB HDD

PSU 650W ( need to be upgraded to 750 if i going to get x2 gpu's not sure yet )

I was thinking of buying x2 6970 ->> = 6990 (the 7000 series were almost there but I can not wait .. am so impatient ...: /

my budget is around 800 euros..

Any tips are welcome..

800 will be crap, but we will see.

my resulution is 1680x1050. but i want to get good fps on battlefield 3 with AAx And HBOA and stuff.


BTW sorry for my bad english. still improving..

a single 6950. take one of the overclocked ones with a twin fan cooler, like the twin frozr III from MSI. and you are good to go. dont give your self a headache.

For an HD 6950 or a GTX 570, resolution of 1680x1050 is nothing. either cards will eat through it. Hell, you can go one step further an get a GTX 560 Ti factory overclocked to 900Mhz and save another $60. and still max it out. a GTX 560 Ti at 950Mhz or so will match both the GTX 570 or the HD 6950 at that resolution.


Cross fire drivers sucks furry nuts. BF 3 Beta and Crysis 2 both run way smoother with 1 card @ 1080P with everything enabled and maxed out. At least for me they did

2 x HD6970's will max it out at your res, so will the HD6990 or GTX590.

The GTX590 has a bad power phase design so not great for overclocking, the HD6990 is apparently very loud under load, thats why I went for HD6970's :) 

Any chance you can overclock that CPU?

omgitzfatal brought something to my attention.

Anything with more power then a single HD 6970 or GTX 570 is a waste. Your CPU wont be able to feed the card with data fast enough.

I have a pair of 6970s with an Intel i5 2500K @ 4.0GHz, and I think the CPU is bottle necking me at this point. Both of the 6970s I have are running at 940 Core.

Hey thanks for you post.

well i build my pc. BUT i never overlcocked anything.

do i need to upgrade my cpu to?
October 11, 2011 7:26:20 AM

sorry to be the barrel of bad news, but if you want cross fire of HD 6900 series cards, then yes. If you stick with one HD 6950, then no.

Could you tell me wich AMD CPU i need ? Amd phenom x6 1100T? if so.

then i going to crossfire x2 6950? i will it max bf3 on my res?.

You don't have to upgrade, you could just get a decent CPU cooler and overclock, you should be able to get 4 Ghz out of it.

If you do want to upgrade then wait for AMD Bulldozer in a few weeks or go Sandybridge

Ye , but as you said with Crossfireing the 6950 will bottleneck the 965?

October 11, 2011 7:40:33 AM

No your 965 may bottleneck the HD6970's/HD6990/GTX590... You'll still be able to max bf3 out, however your framerate won't be as high as it should be due to your CPU being too slow.

I don't think that is much of an upgrade. It's pretty much the same CPU with 2 extra core. As great as that sounds, most games don't use more then 2 or 3 anyway. Wait a week or two for Bulldozer. They would have a model @ $200 that will match the 2500K. 1100T at this point in the game is a serious waste of cash, especially coming from a 965 BE.

But to answer your question, I don't think that will help. But back to what I said before, a SINGLE hd 6950 with your CPU will max out BF at your resolution. But when you drop a second one in, then you will bottleneck. Don't waste your money. I was playing the BF 3 demo at 1080p just now, everything maxed out, smooth as butter on a single HD 6970. not to mention with unoptimized drivers

He said he won't overclock, I wanted to suggest that. But you are right, wait for Bulldozer. He should wait for bulldozer. he wont even have to get a new motherboard.

so.. overclocking the 965 Black edition to 4Ghz wont bottleneck it then?

a 965 @ 4.0GHz should be on par or better then a 2500K at stock speeds. so you would be ok then. that overclock makes all the difference in the world.

The Problem is wich CPU cooler will i need ? and i cannot overclock...

I was thinking of the Corsair H70.

H70 is a great cooler. probably the best choice. maybe even an overkill. I use this one: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

it works wonders for me. I know that newegg wont ship to you, but I just wanted to show you the product page.

Ow ! and i got this Motherboard over here -> http://www.gigabyte.com/products/product-page.aspx?pid=...

this should be good for crossfireing the 6950's right?'

And overclocking with MSIafterburner?

Dont know how to OC.

that motherboard will do fine. you get 8 lanes per PCI E slot when using dual GPUs, so you are good to go.

Overclocking is easy, but MSI afterburner does not play nice with Catalyst Control Center. If you want to use MSI Afterburner, then you should just install the drivers and skip CCC when installing the cards. I learned that the hard way. Dont let any of this discourage you, it is very easy. there are a billion guides online on how to use Afterburner.

October 11, 2011 8:15:39 AM

this too: http://www.youtube.com/watch?v=vWxCcscrrjM

but don't get carried away. increase clocks with small increments. an HD 6950 will overclock to 850MHz easy. after that, you have to go a little at a time (10MHz) and play with the card to insure stability.

but im going to buy from this site. Becaus its in my country ( belgium ) and i get it in like 2 3 days.

But how do i see wich 6950 card is CROSSFIREX READY?

every single 6950 in existence is crossfire ready. every single one can crossfire with 1 or even 2 other 6950s from any brand.

Oh didnt know that ! becus on the boxes of some video cards there is written 'Crossfire Ready' and on some there isnt.

so if i want i could just crossfire these ? http://www.pixmania.be/be/nl/8741652/art/msi/radeon-hd-...

yep, you can crossfire 2 or 3 of these. 3 way crossfire can only be achieved with a motherboard that supports it. your board does NOT. But 2 cards is already an overkill.

do i need to overclock my CPU first to 4.0Ghz before I put my 2 video cards in it?

Becaus some 1 said here im going to bottleneck those @ 3.4Ghz.

ill get an corsair 750w instead. is theyre going to be A Crossfire Birdge in my package ? becuas in my 6870 there wasnt. even with my mobo i didnt come with...
October 11, 2011 9:46:41 AM

In all honesty, even a 955 phenom ii @ 4.0ghz will bottleneck 2 6950s. What will you do with your current GPU, 6870? If you can return it w\o losing money, then its fine. But if you gonna get 2 6950s, and this with losing money on 6870 too, i dont think its a wise decision. See this,
http://www.tomshardware.com/reviews/radeon-hd-6970-rade...

Your CPU will give reduced numbers on 6950s X2 compared to that chart and will give more to 100% in 6870s X2 in relation to that chart. IMHO, i would just get another 6870, because I believe it should be VERY VERY close to your otherwise bottlenecked 6950s X2. So, in summary, OC your CPU to 4.0ghz, and get another 6870. You will get more than 95% of performance compared to bottlenecked 6950X2 AT 1680X1050 resolution and will save you ALOT of money. GL!!

i want get everything out for Battlefield 3.
October 11, 2011 9:57:16 AM

Then you need to buy a whole new setup, and it will cost you alot of money. Are you willing for that? If money is not an issues for you, the best money can buy, and it will play BF3 at max settings is config with i7 2600k with 2x GTX 580s SLI. What is the max you are willing to spend? Can you sell your current build? If yes, for how much money?

October 11, 2011 9:59:01 AM

if you are a gamer then you must go for 2500k with pair gtx 570 and asus p8z68 vpro this setup will kill all of your games in maxed out amd is better also but the drawback is they are not powerful as compared 2500k or 2600k and you want to cf 6970 then this will be huge bottleneck for your gpu's so it can't makes you happy as you are thinking about.with 2500k you can sli gtx 590 or 6990 without bottlenecking and this cpu overclocked to 4.6ghz or above with good cooler so 2500k is the best for bf3
October 11, 2011 10:03:42 AM

You can do one thing though, get just one gtx 580, which will give you enough performance at 1680X1050 and your CPU @ 4.0 ghz will not bottleneck a single big card. SO, yeah, in short, i can say, get a single GTX 580 instead. GL.

no need to for 2600k there is only 100mhz difference in frequency and 2500k can also maxed out bf3 with good gpu and one gtx 580 can handle bf3 on maxed

:)  Yes. I was just giving an eg of what best money can buy. And an OC phenom II wil not bottleneck a single big card. If he is happy with the numbers on a single gtx 580, then thats a good choice instead of upgrading the whole computer. OP, take a look at this again and make up your mind.

im not big fan of Nvidia nor Intel. just because the price is to high.

i selled by moterbike for almost 820 euro. 50cc.

so now my budget is 820 - 850 euro.

well my system spec is now

: CPU: AMD Phenom X4 965 Black Edition@3.4Ghz

GPU: Sapphire 6870 1GB (think it BAD!) It namelijkl DX11 Un-friendly / AAX

MOTHERBOAR GA-MA790X-UD3P (six core supported and CrossfireX)

RAM: 4GB DRR2 ' i know ddr2 but it doesnt affect the fps.

1TB HDD


i dont want to sell my whole setup.. i mean i could sell it maybe but in parts then. like my 6870 Sapphire edition which is a crap card..

if i could sell my whole setup then i may change to intel and invidia.

But wich CPU Wont Bottleneck the x2 6950's ?.

Six Core's wont bottleneck it then? i dont mind buying a six core since its only 179 or something... but also i dont want to spend 180$ on a six core from amd that isnt better then the 965's ive heard..

No, just NO. 1090T WILL be as much of a bottleneck to CFX cards. IMHO, get atleast a 2500k for intel. And nvidia fares better in bf3.

open the link and see the difference between 1090t vs 1100t.phenom 1100t is slightly better but 1100t benefit is if you want to cf big cards then it will fine with 1100t not sure on 1090t.

professional gamers do sli gtx 590 or 6990 that's what i told you 2500k can handle 2 6990.

and i have sli gtx 580 all of my games on maxed out
October 11, 2011 11:22:57 AM

Well, since you are adamant on NO nvidia, just get the 2 6950s CFX, see if your CPU is a big big bottleneck or not? Some games, like Metro 2033 show lil bottlenecking by cpu, but games like starcraft ii and crysis will show huge drops. Just hope BF3 is like Metro and not like crysis. GL. Just get the 2 6950s and be done with it. DO you have the beta of BF3?

that's what i told him he has only three options
1:if he doing cf 6950 then cpu will be bottleneck.
2:if he doing cf 6950 than must go for 2500k
3:with one gpu he would be fine on his current cpu
