My mainboard only has a AGP4x slot. It is quite hard to find a "new"(not used) AGP4x card, is it possible to make AGP8x card work with AGP4x slot?

I think all agp8x cards work in agp4x slots (except the 9600Xt if I'm not wrong) and the performance is the same. So not to worry on that.

P4-2800->FSB800, Asus P4P800, 512DDR-400, Creative GeForce DDR (the first one lol)

Thanks a lot! But..., what do you mean the performance is the "same"? What's the benifit of a AGP8x mainboard slot?

All 8x cards work in 4x slots. Most 8x cards will work in 2x slots.

Cards that won't work in 2x slots include the 9800XT and 9600 series. I haven't checked anything newer.

But he only asked about his 4x slot.

Wusy, I am pretty sure it is less than that in most situations. My 6800GT, on a 4x AGP motherboard, scores almost as well in 3DMark05 as the same card on an 8x AGP motherboard. There is only a 3-5% difference. Top end cards are just beginning to saturate the 4x AGP bus.<P ID="edit"><FONT SIZE=-1><EM>Edited by Acert93 on 12/19/04 11:32 PM.</EM></FONT></P>

I've teste it with my 9800Pro before it burned away, and the diference between 4x and 8x was none. At least at 1024 with 4x AA and some Aniso. I think even the newest cards don't use that much bandwich.

I already told you, you were wrong, or at least mistaken, in your statement. You don't have to believe me, but you do have to shut up about it. Or at least ask for an <A HREF="http://www.sysopt.com/articles/agpupgrades/index.html" target="_new">explaination</A>

The last post was not for you crashman. It was for the other guy that thinks it's superior. Where is my statement wrong? I've checked for that 9600XT issue of not working in agp4x here in Pt and the answer was always the same. do you know anything about this issue?
I recall reading it here at this forum some time ago but can't seem to find it anymore.

9600 series works on 4x and 8x motherboards. 9800 series, except for the 9800XT, works on 2x, 4x, and 8x boards. 9800XT works on 4x and 8x boards. There's a link to an article in my last post.

Didn't I give you a link to an article that explained everything? If the card fits, the card works, all 8x cards work in 4x boards.

You'll notice that the article goes from upbeat to straightforward to upbeat again and has a few very minor flaws, that's because it was modified by my editor :smile: He's a great writer but I wish he'd have given me the opportunity to smooth it out after his revisions. Or he could have rewritten the whole thing to make it match his own style and credited me as a co-author.
