Which is better AGP or PCIe? Is AGP new making PCIe obsolete in the near future? Was also looking for a motherboard to hook up a AGP card and couldn't find anything in the specs on where or how it plugs in. Thanks a bunch.

PCIe is newer and AGP is being phased out. Very few new motherboards have AGP

PCI-E is the standard these days ... In the specifications, look for "expansion slots" which tells you what graphics interface the motherboard supports. For example, here under expansion slots, it states that it supports PCI-E which is not compatible with AGP. Therefore, you'll have to search for a motherboard that has a AGP slot. Hope that helps ...

AGP performs marginally better, but when you consider the fact that any new upgrades would be to a PCI-e card and that PCI-e offers extras like crossfire and SLi, PCI-e is definately the way to go.

AGP performs marginally better(fraction of a percent), but when you consider the fact that any new upgrades would be to a PCI-e card and that PCI-e offers extras like crossfire and SLi, PCI-e is definately the way to go.

to put this in terms that you understand, PCI-e is cheaper, more future proof, and has extras, and more extras, while AGP has an increase of a fraction of a frame/second.

You shouldnt of because in terms of bandwitdh its not true.

Apples to apples if you compare the exact same card in AGP and one with PCIE, on modern games you should not see a differance in FPS, but probably next gen games PCIE is going to start to shine due to the extra bandwidth.

Yup, At this point in time I don't know that anything out has fully utilized all of Agp's bandwith, But Pci-e does indeed have more room to grow.

y7ou currently dont even notice any difference when you compare AGP 4x to AGP8x.. yet alone AGP8x to PCIe 16x.. lol

games have just started to take advantage of AGP8x's bandwidth.. not full advantage tho.. so it would be a while till games starts taking advantage of PCIe 16x's bandwidth..

from what I've read though, AGP performs marginally better than PCI-e, though the diference is more or less negligeable(it's the result of a changed bus process, but in the future when you need more bandwidth the diference will be more noticeable). I'd post the link to the review I read,but th forum which I saw it on is switching servers as of this moment. As I said though, it's more or less negligeable. PCI-e is the way of the future.

i think the bigest reason why pci express might not perform upto its full potential rite now is the high end pci express cards will be bottlenecked by the rest of the system to a certian degree. but i dunno, i would think pci express to perform better rite now.

I thought I had read somewhere that in head to head Pci-e had a 2% performance advantage over Agp. It's been quite awhile since I read it so I could have faulty memory plus I don't know how accurate the information was.
