4x or 8x AGP?

what's the diff? I just bought a biostar m7VIG mobo with a 4x AGP expansion slot. what does that have that a 4x/8x agp expansion slot doesnt?

2x the bandwidth, any modern card should work, but don't put in to fancy of a card or it will be bandwidth limited.

NVIDIA GEFORCE FX 5500 256MB AGP 4X/8X

that would get band limited right?

probably not :) i'm pretty sure the AGP bus was never saturated before pci-e came along... but the 5500 is a pretty weak card, perhaps look at a 6600gt if you can stretch?

I've never seen anyone able to show much of a difference between AGP 4x and 8x in terms of performance, as above the available bandwidth was never saturated.
I'd also recommend a better card if you can afford it, a nice 6600GT would do you well :).

The full AGP bandwidth was not needed until AGP was obsolete. Preformance tests found negliable difference. The one concern I would have is with a briged card from say the 7900 series.

Hmm but would a AGP 8x card work on a AGP 4x mobo just want to know will it do something to the mobo:O_o1:

Yeah, I think all AGP 8x cards are actrually 4x/8x the voltages are the same unlike with 2x and 1x. Look at the finger position to verify/ look at the specs.

All AGP8x cards will work as AGP4x afaik :)

Nope :)
4x AGP is 1.5V
8x AGP is 0.8V

You need to check the mobo. If it doesn’t support 8x AGP, it'll just run at 4x AGP speed - not that its a problem :)

Hmn.. but I recall my 6800GT runs 1.5V so in theory it should be fine even with 1.5V 4x voltage..

Yeah most 8x cards are fully compatible with 4x. It's actually going the other way that's more of a problem, for example running a 3.3V AGP card in a 1.5v AGP4x slot.
