Need help about compatibility for new build!!

[rapolitas]

Hi guys, i'm building a new PC from mifcom.de In the site you can choose the parts you want for your pc. I'm getting the AMD Phenom II X4 955 BE cpu and Gigabyte GA-890XA-UD3 motherboard. Now, in the site, you can take the GTX560 ti for 256,00 €. But from amazon.de, you can get the 1GB MSI N560GTX-Ti Twin Frozr II or the 1GB Gainward GTX 560 Ti Golden Sample for cheaper prices. But i'm not sure if they will be completely compatible with my new build. And will I be able to run 2 cards SLI with that motherboard later on? And if the GPUs from amazon are compatible, which one of those is better? Actually, if neither are good, just look at this and tell me which one is the best (and if its compatible with my system) http://www.amazon.de/s/ref=nb_sb_noss?__mk_de_DE=%C5M%C5Z%D5%D1&url=search-alias%3Daps&field-keywords=GTX+560+ti&x=0&y=0

The 890X is an 8/8 crossfire capable board so if u thinking multi GPU

1920 x 1080 AND lower HD 6850/6870 with view to CF
2560 x 1600 with Eyefinity plans 2GB HD 6950 with view to CF

not sure on the continent but in UK CF-able AM3 could be had for really cheap like the Asrock 870/880G Extreme3 models

But I'm getting nvidia, and as far as i know, with nvidia its SLI, isnt it?

 

[rapolitas]

And I live in luxembourg currently

Out of the box, 890X chipset cannot do SLI but there are ways to do it ^^ Look for a 750a chipset?

 

[rapolitas]

*** it cant??! ***! There are no 750 chips on the site im buying. What are the ways to do it though? Is it very difficult? Cos i kinda want to upgrade in the future and add another GTX560 or something.

If you 100% need CUDA then stick to grren camp else 2GB HD 6950?

But wait, there’s more. What about the Radeon HD 6900s in CrossFire? After all, AMD claims to have made some notable improvements to its scaling.
You’re only going to buy two high-end graphics cards if you’re running at the top resolutions with visual details maxed out. That’s where the 2 GB frame buffers featured on both 6900-series cards come in handy. In many cases, two $300 Radeon HD 6950s outperform a pair of $350 GeForce GTX 570s, saving you $100 total for better frame rates.

Unless you're a die hard nvidia fan or want CUDA or physx, there is no reason to go with nvidia over AMD. AMD scales wonderfully and preforms just as well. The main difference is the technologies. CUDA and physx with Nvidia and Eyefinity with AMD.

As for which card is better - I tend to like EVGA cards. They have been reliable for me and good overclockers. Any of them would work in your system.

To use SLI with an AMD processor, you will need an Nvidia chipset. There aren't many options out there. I would ask the site you are using if they offer any options for SLI with an AMD processor. They might not.

I dont know what CUDA is so i probably dont need it. So with the current mobo Im getting I wont be able to put 2 nvidia cards in? only amd like the HD6950?

As said w/o a 'hack' AMD/CF only so ya

Talking about this?

You could find something close to that rapolitas

EDIT: for pre-built, you could go for this
http://www.mifcom.de/product/530/1/high-performance-gaming-pc/pc-system-phenom-ii-955---gtx470.html
It has a pretty good processor and the gtx 470's performance is very close to that of gtx 560

And if u have more money to spare you could go for
http://www.mifcom.de/product/688/1/high-performance-gaming-pc/pc-system-phenom-ii-965---hd6950.html
The AMD 6950's performance is on par with gtx 560, but it out performs gtx 560 on higher resolutions ( and its a 2GB card). Finally u could bios flash the 6950 to 6970 which makes it a killer card.

 

[rapolitas]

So then I'm going to go with the HD6950 since it can go CF. But then the same question arrives: which one of these is the best and will it be compatible with my build? http://www.amazon.de/s/ref=nb_sb_noss?__mk_de_DE=%C5M%C5Z%D5%D1&url=search-alias%3Daps&field-keywords=hd6950&x=0&y=0

 

[rapolitas]

AND will I be able to run CrossFire with another card like that?

 

[jedi940]

The differences are whether the card is overclocked or not and what accessories come with the card. I have had good luck with Sapphire in the past. XFX offers a lifetime warranty on the card. Really, the choice is up to you. Any of them will work fine and crossfire.

 

[rapolitas]

Lots of reaserch to be done, then. Thanks

 

[rapolitas]

But I just took a look at some, and basically all of them have the same core clock speed as the stock card: 800Mhz. So wtf? They seem quite similar, just as fast as the stock card. So which one should i go for?

 

[rapolitas]

Asus 6950 seems to be the only one with higher factory clock which is 810 Mhz. But 10 doesnt really change a lot. So which one should I go for?

 

[batuchka]

If i were you i would place distro support and dependability as a buying choice as well but am not familiar with distros where u at

Also check whats in the box, i.e accessories included in th box when u purchase the card
