GIGA mobos reduce PCI E lanes to 8x , what about ASUS ?

[8Vidia]

Hi people , as peolpe say :
ASUS mobos dont touch the VGA PCI e lanes when they have USB 3.0 , BUT GIGA mobos Reduce PCIE LANE to 8x ( which means slows done the VGA card )

I dont know it means that ASUS make VGA cards work faster ? but Because GIGABYTE mobos reduce PCIE LANES they make VGA cards work slower

Questions about ASUS & GIGA MOBOS are these:

1.do they make difference in Performance of VGA cards
2. if yes , then , when does that Performance Drop happens ? while using USB 3.0 ?

3. after all , which one makes better place for VGA cards , & let them to fully get used ?( for example ATI 5850 ) .

First, PhysX is an nVidia only option - http://en.wikipedia.org/wiki/PhysX

Next, "The PCIEX16 slot operates at up to x4 mode when ATI CrossFireX is enabled." Single GPU - "*1 x PCI Express x16 slot, running at x16 (PCIEX16)" Yes, you'll loose some FPS in CF, as far as how much; review the article again and find a similar or same games you play.

The following example is a GTX 480 {x4, x8, x16}; faster GPU:

Ok ok , Question was this , just answer : i Heard that if i USe SINGLE 5850 then 8X to 16X is to Diffrente . so its to important to me to know that my mobo will run it at 16X & will let it to fully get used & showed UP . CAN GA P55A UD3 run it at 16X ?

IF not then suggest me similar MOBO which has same or lower price & can run it at 16X . please !!!

On a SINGLE GPU = x16; ANS Yes.

On Two (2) GPUs = x4; ANS No.

OH THANKS A LOT !

Can u say which one of these Producers of MOBOS , use NEW technology which make PCI lanes ( slots ) run COOLER & FAST ER?
ASUS or GIGA , which one has that technology ? lets say on this models if not just say ASUS or GIGA ?

ASUS P7P55A E or GA P55A UD3

 

[jaquith]

^ That's a new one, they are both running the same 'technology' - ASUS has less of a problem managing heat than Gigabyte {my experience}. The 'new' technology coming 'soon' is PCI3 3.0; effectively doubles the speed of PCIe. Is that what you are referring to by "NEW technology"?

Ya something like that , I realy dont know which one is better finaly , as i saw GIGA has more abilities & technologies , some peolpe say GIGa & other Say ASUS , GA P55A UD3 & P7P55A e ASUS have too similar specification , & if we want to compare & know which one is better at all , we should take a look at the Technology . But away , isnt new Mobo PCI slots 2.0 Version ? & which mobos will have 3.0 version , When , how much theire prices will be , does it worth to wait till they come out


PLEASE ANSWER ALL QUESTIONS , not just one , that i wont ask same question 100 time , THANKS

1) Current specification is PCIe 2.0 x16

2) PCIe 3.0 specifications are to be finalized later this year and after that you'll be looking at another 3 to 6 months for them to hit the market. All board makers will move to PCIe 3.0 at sometime.

3) No, it isn't worth the wait as current cards don't saturate the current bandwidth.

4) Expect to pay higher than current prices until it becomes more main-stream & every board has it.

First, I personally won't choose either MOBO. My preference for ANY Intel is EVGA, and then ASUS, next MSI and dead last Gigabyte. And I did say, "ASUS has less of a problem managing heat than Gigabyte" - so I don't know WHAT I'm MISSING???!

All of these MOBO are PCIe 2.0, exception EVGA P55 FTW SLI | 132-LF-E657-KR PCIe 2.1.

Out of the mix I only can recommend the ASUS P7P55D-E Pro, and after that then neither of the (2) MOBOs would I recommend. I know you're making a regrettable mistake over $30 USD.

Personally, I like the EVGA P55 FTW SLI | 132-LF-E657-KR, but I'd settle with the ASUS P7P55D-E Pro. I would NOT build off either the ASUS P7P55D-E or GA-P55A-UD3. Gigabyte has known H/W issues with the Intel chipsets. I see 10:1 Gigabyte unresolvable problems to ASUS in this forum.

Further, PCIe "temps" is an non-issue with either Gigabyte or ASUS; ASUS overall runs cooler.

PCIe 2.x vs PCIe 3.x - According to you, and the $30 decision, I seriously doubt that you would spend the extra $50+ to $100 for the PCIe 3.x, and if you did with (1) or (2) CF mid-level GPUs then you'd be totally wasting your $!

What more

 

[jaquith]

The point you are missing is that your GPU will barely if even saturate x4 PCIe, not to mention x8 and FORGET about the x16 - not even a dent!

In BOTH posts you are arguing over nothing. Now IF you through in 3/4-WAY GTX 480 OC then it would be something else to discuss!

U can answer in next thread JAQUITH , & the other answer is : so if it doesnt worth to wait till PCi 3.0 comes up then i can easly buy one of those mobos .

I think they are good if i do this things :

1.no SLI
2.NO CF
3. no overclocking
4.using single 5850 at 16X under 1440 rez

according to my needs say which one is better from those 2, please . finaly answer the CORRECT QUESTION ,

 

[8Vidia]

Who wnats to get GTX 480 ? me ? oh man come on look more carefully , & say why Single 5850 cant run at 16X on 16X pcie slot ? JUST A SINGLE 5850 i am talking about , NO CF , SLI UnDERSTANDx1000 ?
