PCIe 1.0 to 4.0, What's the differance - how to tell??

Posted 08 October 2012 - 07:07 PM

This computer that I'm rebuilding has a PCIe X16 graphics slot, so I am looking for a great video card to put in there. Only thing is my motherboards manual says nothing about the per-lane data rate?

After reading the Wiki page I'm guessing that the per-lane data rate is backward compatible, so A 3.0 card would still work if my motherboard is only 1.0...

But I'd rather have assurance before spending $200+ on a video card.

What do you guys/girls think? Has anyone done/used this?

Well this guy was able to successfully run a GeForce 240 GT (PCIe 2.0) in his Precision 670, so that's a good sign. This confirms it too. Wikipedia's entry on PCIe 3.0 says the standard was made to be backward compatible with all existing implementations. I did see a few threads floating around saying people were having problems putting newer cards in older motherboards, but that wouldn't stop me from trying. It's not like you can't return the card. There may be BIOS updates relevant to the newer standards, so be sure to check the support website. You'll only get the 1.0 performance, so buying a high-end card is not wise.

I went ahead and got me this video card:

The computer I'm putting it in is almost 6 years old.

Now to buy a hard drive :)

No, I didn't see the box until I got it in the mail.

I went by Memory size, GPU speed and overall physical design.

Edit, But the sword is cool though, definitely a deal breaker!

There won't be a compatibility issue, but a 7870 will definitely be bottle-necked by pcie 1. Your hard drive is even worse. A 6 year old motherboard will still have ide ports, and all modern drives are sata. These are completely incompatible, and I have heard that most of the connectors are not of great quality. You might want to just get a cheap motherboard and processor at this point. I know it is painful, but it may be the best choice by now as the processor will start to become insufficient for gaming soon.

Umm, what the heck are you talking about?
  • 1> this "WORKSTATION" has dual 2GHz CPU's
  • 2> The mother board has SATA, SCSI, and IDE (Did you even read my post? there is a link to the systems specs)
  • 3> I bought a 6770 (PCIe 2.0 so if it gets dumbed down, it won't be by much) where did you get 7870 from?
  • 4> This is a workstation, after market motherboards will not fit in this case.
  • 5> It will coast way to much money to buy "todays" equivalent of this motherboard and CPU set.
  • 6> I have a cheep mother board and CPU, and I'll tell you this, cheep motherboards are a waste of money.
  • 7> "insufficient for gaming"? it runs TF2 just fine....
  • 8> I'm running 8gigs of ram, I think this system can take 64gigs total.

sorry, got the 7870 by misreading the type on the box. I did not read the external link because I didn't see it, but I assumed that since it was pcie 1, it would not have sata. I was wrong there. Looking at the specs, I still do not see dual processor, but I may be wrong there. Wow, just looking at a hard drive history, thought sata was at least 2008, it's actually 2002
