Whats the point of having 2 PCI-Express 16x slots if you can't have SLI/Crossfire? Can you run a regular PCI card in a PCI-Express 16x slot (is there an adapter?). I take it all PCI cards will eventually be upgraded to PCI-Express since PCI is phasing out. But besides an Audio Card and Physics cards (which are debated not to do anything in gaming) what else would you use a regular PCI slot for? I'm looking at this one mobo and I don't know if it's worth it... Answering these questions will help me alot.

If your curious I'm looking at this mobo: http://www.newegg.com/Product/Product.asp?Item=N82E16813127235

None, but as it's becoming popular manufacturers just put it in.

Not really, in a few years time other devices might benefit from x16 PCI-E slots, physics processing for example, or a RAM bootup card. High speed data storage is another possibility. While it's basically a fairly useless sales tactic right now, that doesn't mean it won't be useful in the future.

I lay upon my bed one bright clear night, and gazed upon the distant stars far above, then I thought... where the hell is my roof?

Yes, but by then there will be a new slot that does even more. Time to upgrade again...

How long ago was AGP introduced? How long did it take for it to be made obselete? It was a good few years.

a second pci-e x16 slot will allow you to use another graphics card if you want to run 3 or 4 monitors, also the s3 chrome27 cards will do multichrome (it's version of sli) on any board with more than one pci-e slot but one mid-high range ati or nvidia card is better than even 2 of them.

also ati/nvidia may one day relenquish their lock to their own chipset allowing sli/crossfire on any motherboard

edit the one you linked to is crossfire compatible

im still waiting for any cool pci-e 1x devices, which have better bandwidth than standard pci. I think any add-on card could benefit from this. A good candidate would be high end audio cards with all of the fancy multiple inputs etc. last time I checked I didnt see anyone like M_Audio or anyone with pci-e cards, everything was still pci

its 9/11 - but its FAKE 9/11

mm0zct: Holy crap, why did I think that it wasn't crossfire? I was comparing so many different motherboards at the same time though. Maybe I just got mixed up.

CattleRustler: Yea that brings up another good question. Whats the use of a 1x slot? What in the world would you plug into there that is currently out? Is it just a pioneer technology that might not make the cut (like blueray)?

gigabit ethernet cards i've seen for pci-e 1x and sata2 controllers require pci-e 1x as pci doesn't have enough bandwidth. there's also low end graphics cards for pci-e 1x

Interesting, I've never even heard of 1x until I did some research recently.

I've decided to go with the GIGABYTE GA-965P-DS3 mobo and the Intel Core 2 Duo E6300 1.86Ghz (Can be OC'd do 3Ghz!!!).

yeah, the mobo I have has 3 pci-e 1x slots, aside from the 16x slot for video, and 2 standard pci slots. I was all like "wooo, cant wait for some new devices for pci-e 1x...". But now I'm all like

One thing I've learned is to ignore what people say about overclocking... If Intel could sell that chip so it ran stably at 3Ghz, why sell it for 1.86? The reason its at 1.86 is because thats the maximum it could run at before producing errors... I had a Barton 2.5 whic is identical to the 3.2... I put it at 3.2 and 99% of the time it was fine - but just when I didn't want it to crash, like mid-game or mid-dissertaion, it would lockup and crash. At 2.5 it was 100% stable.

Bare that in mind

Hardware Specialists say that overclocking is basicly overworking your processor, and is just a term that was used to sell old processors. Ocerclocking is the devil.

Be glad you got PCI slots instead of my ISA slots, my computer is old!

There is a pci-e 1x video card, but I can't imagine why...

Linux terminal? lol

One thing I recently learned - PCIe and PCI-X are VERY VERY different technologies!!!

PCI-X is commonly used in server's.. PICe is mostly in desktop machines. I bought a SATA2 RAID card which was labelled PCI-X and I thought the -X bit was just another way of saying eXpress... Only when I opened the box did I see the slot was a very different length and the pin layout was different too!

It is like CattleRustler said...the bus gets faster, and older cards won't keep up. Wait states are useless when you need millions of them, the system would essentially hang while waiting for the I/O to complete. When PCI first came out, it was 33MHz. What is the FSB now? 533Mhz?

Bleeding edge blues, my friends.

pci-x is basically the next evolution of theoriginal pci bus, it's basically a 64 bit (hence double length) pci slot that can run at higher clock speeds.pci-x is fully compatable with pci cards and some pci-x cards will function, just slower if you plug the first part into a pci slot and leave the rest exposed.

pci-e is a completelynew technology that has nothing to do with the original pci standard. it's a serial connection rather than parrallel for a start (pci-e x16 is 16 serial lanes for example) iirc pci-e was also previosly known as 3gio (3rd generation input output)

800 no? I forget

pci-x, basically useless and injected into the market as a confusion factor, like all of the video card models that basically suck, mx vs. ti (nvidia) is a great example. people thought they were getting a good deal in an mx card because it had the key numbers and catch-phrases, little did people know it was a shite card compared to a lesser ti.

pci-e 1x video card? cool. it'd be better than a pci standard, and comparable to a middle of the road agp card.

Its 9/11 - but its FAKE 9/11 Ts=SQRT(Df/16)
