PCI Express v1.1 16bit compatible with PCI Express 3.0 video cards?

steve-kj · Aug 18, 2014

My Dell Inspiron 530 has a OFM586 motherboard.
According to HWINFO, the PCI Express version is 1.1

I got two questions:
1) Will a PCI Express 3.0 video card be compatible with my motherboard?
I guess it probably will since my previous PCI Express 2.0 video card worked fine on it, until it recently died.

2) How much of a reduction in performance will I experience by using a PCI Express 3.0 video card on a v1.1 PCI Express 16-bit slot?

a ton of performance loss but oh well. pci-e 3.0 cards in pci-e 2.0 x16 slot is like running in pci-e 3.0 x8 however you only lose 1-2fps but on 1.1....yeah.

A PCI-e 1.1 16x slot has the same bandwidth as a PCI-e 3.0 4x slot so depending on what card you are getting you could take a significant performance hit, but a lower level card shouldn't take a big hit. It also depends what you are using it for, standard multimedia tasks don't require much GPU bandwidth and won't be limited by the bandwidth of the slot at all.

So in terms of value, I should try to stick to pci-e 2.0 video cards like my old one?

There's no point in spending big bucks on a fancy pci-e 3.0 video card that would suffer from performance degradation on a old motherboard like mine.

well just upgrade your mobo to a new pci-e 3.0 card. you can get like a i3, a z97 or h97 and get that card later.

My purpose is "light" video gaming.
My computer doesn't have the components for dual SLI video cards, which is for serious gamers.

Would you be able to please provide some specs that I should look for in a low end pci-e 3.0 video card, and also which specs I should avoid in a high end pci-e 3.0 video card?

Thanks.

Going that route, I might as well as build me a new computer.... or if I win the lottery, then shell out the big bucks for an Alienware gaming PC!

LOL.

Alas, I intend to keep my old mobo as long as possible.
Any suggestions for a PCI-e "value oriented" video card would be great, thanks.

For "light" gaming you might not take a massive hit. What card were you running before? An equivalent PCI-e 3.0 card won't need much more bandwidth.

You are probably look at something around the GTX 750 level.

yeah since your light gaming the r9 270 is a great card that will have some great performance despite being in a pci-e 1.1. its also the same price as the gtx 750ti. (lol pci-e 1.1 is old, 4.0 in 2016.)

I had a Galaxy Tech Nvidia GEForce GTX560 GC 2GB DDR5 256bit.
Worked fine until recently.

I contacted the vendor for hardware support, and even gave them a PDF copy of the invoice from newegg.
However, they couldn't verify the original date of registration, so it looks like I'm going to buy a new video card.
Their standard warranty is 2 yrs.
Extended warranty is 3 yrs, which I have/had, but vendor can't verify.

This isn't right... the 270 will be hit pretty hard by the limited bandwidth, and is notably more expensive than the 750 Ti, the 750 Ti comes in ~$130, the 270 comes in ~$160.

The GTX 560 you had before is pretty comparable to an R7 260X or a GTX 750(non-Ti) if you want to stay on the same tier. I would question the usefulness of stepping up much higher as you will start getting bottlenecked by your board and your CPU.

hunter315 :

I'm no expert like you guys, but all that sounds fine to me.
The 750 Ti it is then, unless someone else wants to make a strenuous objection, or some other suggestion.

Thanks.

it will have a 5-15fps hit but it still will be okay depending on what he gets. the r7 260x is what i recommend instead of a 750. also the r9 270 has sales at 139-150$ around the price of a 750ti.

All that sounds great too.
Like I said, I'm no expert like you guys.

Will comparison shop for a r7 260x too.

Thanks.
