What is SLI/CrossFire , Crossfire ready And What Does it Do ?

sli when your run two of the same nvidia video cards in the same machine using an sli bridge. they have to be the same gpu, eg gtx 780.

crossfire is amd's version of sli, works pretty much the same.

a crossfire ready motherboard supports crossfire configuration only, can not run nvidia gpus in sli, a single on is ok, but not w

Sli/crossfire means you can run either sli or crossfire on that particular motherboard.

sli or crossfire will improve your video performance by ALMOST double, in most games.

So I Need To Buy a CrossFire Ready MotherBoard To Run 2 Radeon GPUs ? , Must it Be The Same GPU ?

SLI = Running 2 or more Nvidia graphics cards in a single PC to boost graphics performance.

CrossFire = Basically the same as SLI, but with AMD cards.

What are the differences?
SLI only works with identical GPUs (2x GTX 770 for example), but the manufacturer (Asus, MSI, EVGA) doesn't matter.
CF is a bit less selective; You can Crossfire the HD 7970 with the R9 280X or the HD 7950. Everything will work as long as the cards use the same architecture.

Remember, having 2 cards doesn't double the performance; Some games get a performance increase of 80% and others will not benefit from it at all.

The problems?
SLI tends to have worse performance scaling than CF, but it has less problems like microstuttering. If possible, always get the single most powerful card you can afford, that way you can avoid these issues.

Yes, the motherboard needs to be CrossFire Ready for crossfire to work or SLI ready for SLI to work.

What GPUs are you planning on using together?

i have run both sli and crossfire setups, and i agree with Eduello with everything except the last statement, i have always though sli scaled and just plain worked better than crossfire. im not saying he is wrong, i just have had way less issues with sli than crossfire

Im Just Asking To Get A Good LGA 1155 To Upgrade My Specs Later Specially The GPU I Will Get R7 260X 2GB GDDR5

Yeah, I don't have personal experience with either (yet), but SLI does have less issues, at least it did in the past generations (from what I've heard/read). I've heard that AMD has really stepped up their game with driver support and fixing issues with CrossFire with their R9 cards though.

What is your budget with the motherboard?

 

[Salem Sayed]

500 L.E , I Dont HowMany Bucks is That Now Check This Website http://www.egprices.com/

 

[Eduello]

Sorry, but this is the cheapest motherboard with CrossFire support that I could find on that site: http://www.egprices.com/en/product/gigabyte-ga-p75-d3-socket-1155-motherboard-el-hady-for-trading-company

Thanks Eduello , Thanks Bradley

 

[Eduello]

No problem
