i currrently have a motherboard that only supports agp 4x. i have a GeForce FX 5500 OC 256MB 4x/8x graphics card though. if i got a mobo that could run my card under agp 8x would there be a notable performance increase?

A bigger pipe always gives better performance, as rule. Though I don't have a 4x slot to test it out.

would doom 3 perform noticably better?

I do have one and it's certainly faster. I tested it switching from 4x to 8x thru the Coolbits2 (http://www.nvnews.net/vbulletin/showthread.php?t=29541) registry trick.

well if thats the case then take a look at this mobo that im considering buying. it suits my current 2.4 celeron and 512 pc 2100 RAM. its got agp 8x and looks pretty tight but its refurbished so i dont know if i should. tell me what you think of it and whether or not i should go refurbished.

Sorry about the delay. Well, the mobo itself is ok (even if it was a little more expensive it would still be ok) and could make a good purchase if it wasn't refurbished. I wouldn't get something like that if I had some other choice but if you don't, go for it, it might not last as long as a new one would, but you can get the best out of it with your video card and vice versa.

A bigger pipe never hurts but it isn't guranteed to help either. Look (http://www.hardwarezone.com/articles/articles.hwz?cid=3&aid=604) for yourself. Only in the most extreme situations is it going to make a differnce. If you had a 6800/x800 things might be a little different but not with that 5500. But it wouldn't be a bad idea getting that mobo anyway since it has dual channel memory (but you won't be able to overclock since its an Intel board).

I must disagree completely, 8x is faster,I've done my tests too and my card ain't as good as a 6800. People can try it out.

Best reults are of couurse, much more intense from 2x to 4x but 4x to 8x aren't bad at all.

well everyone's mialage is different. While it certainly didn't help my 9600 Pro or even my radeon 9000 Pro, I noticed a slight increase in my 5900XT before I modded it to a 5950 U (which took me down to 4x with higher scores actually, due to the higher clocks). Now with higher end boards, you get more performance but its generalls noy that spectacular. Sometimes it ranges on the margin of error. Now while it may have increased the speed for you, it doesn't mean it does for everyone else. If you can provide adiquate research that supports your claim that it increases in all cases then please give a list. It has a wider pipe, does prodive a small increase and is only logical that you enable 8x but its not as significant as you make it sound.

I'll eventually post whatever I get to test, so far I can only speak for a couple of PC's which I think were somehow benefited, but that's pretty scarse to be taken as a rule.

I guess I read into your last post too much, I agree with your current post. There IS a performance benefit but its minute (depending on the machine and circumstances). I believe that higher end cards are affected by it much more then mid range/lower range cards are as they are more limited but the performance benefit is nothing to write about.
