AGP 8x on 4x mobo

I need to update the graphics cards on my old PC and on Kev's 2 1/2 year old Shuttle.

Will an AGP 8x card run on a mobo that only supports 4x (one web site claims it will)?

Which is better for gaming Radeon 9600 with 128mb or Radeon 9550 with 256mb?

(I'm not looking at Nvidia chipsets because some of them don't fit inside the Shuttle... but although the compatibility list on Shuttle's web site mentions this it doesn't list which cards will not fit).

Will run but only a 4x speed

Will an AGP 8x card run in an AGP 4x slot....YES.

Will it run any slower in an AGP 4x slot.....unless you put something in it like a Gainward BLISS 7800GS+ which is the fastest AGP graphics card ever built,the answer is no it wont run any slower.

Personal experience with an ATI X800XT running at both AGP 8x and 4x showed no difference in Benchmark scores or real gameplay......something like a 9600 class card wont tax the AGP 4x bandwidth,let alone 8x.

Of the two cards you mention there is little to choose between them......but for any more up to date games 256MB of onboard memory is probably best.

Have you looked at a more up to date card like the ATI X1600pro?.The 9600/9550 cards are both a bit long in the tooth for up to date games.

Remark:* Due to mechanical incompatibility, some NVIDIA chipset based cards (such as Msi FX5900 in the list) are only working with chassis cover
open.

As you can see they warn that one of these won't work with the chassis cover closed (I read on one site that they are too fat) but don't say which others (if any) also have this problem. I've had a look at some reviews of the machine to see what other people have put in it but as the 9600 was state of art at the time I can't find anyone mentioning anything better :-(

My old PC is still running Win 98SE so although card size wouldn't be a problem OS support might be!

I agree with the others, speed will not be noticeable between a 4x AGP slot and a 8x one. From the 2 cards you originally listed I personally would go for the 9600 as its a better card than the 9550. I an assumming the card is the 9600 Pro, it does make a difference. Of the others listed the MSI 5600 is an excellent card though it may be differcult to find as its a bit old. I did find this click here but you would have to check it would fit as it isn't in your list. The listed MSI one the FX5600 TD128MB is better than the one I linked to above but its still a good older card.

In the reviews on Ebuyer someone had overclocked a Connect3d 9550 256mb card and said that he got a 9600 pro from it. Does that sound right? As the case space is limited might overclocking cause overheating?

The 4x and 8x speeds of AGP cardz are not, as might be logically imagined, linear.

I discovered a Shuttle newsgroup so I posted there to ask whether anyone had put a more recent card than a Radeon 9800 in this model.

It turns out that the problem is with this case that the graphics card ends up crushed against the case so the cooling fan has to work much harder (and cards with fatter profiles don't fit at all).

One guy is looking for a newer card for his own Shuttle so I'm hoping that he'll get back to me with his choice.

Now back to my old PC with the AGP 4x. Now that I know that I can run an 8x AGP card on this machine what should I be looking out for. I've only seen a couple of cards that state that they will run under Win98SE but can I take it that most AGP cards will do? Should I only be looking at older cards if I can't find anything that says for sure that they will run under 98?

What I thought that I might do is buy a card for the Shuttle then if it doesn't fit I might be able to use it in my machine.

Looking at photos of various cards the Sapphire Radeon X1300 256MB seems to have as low a profile as the ones that I know fit in the case click here
