AGP Aperature Size

I have been wondering about this for a while and I read up on it a lot and apperently, if I know how to read correctly but I am not sure that I do, it has to do with your system memory and not your graphics card memory. The higher you up the AGP aperature the more system memory you are using in conjunction with your graphics card so if you have a really good card like the 6800 GT you would probly want to put it at 64 MB. Here is what I do not understand though because everyone I asked told me to put it at 256. Depending on how much system ram you have I would say that it is all about testing it yourself. Change it, go to a game, see if its better when its higher or lower. It can't hurt your card so you really have nothing to worry about.

why not trying it at 62,128 and 256 and see what gives the best performance.
I did that and found 256 was best for my system.

In short, bigger is better.
Just don't set the AGP aperture too high if you don't have enough main memory.
If you have 1 gb or more, I suggest setting it to the max (usually 256 mb).
If you have 512 mb or less, you may want to set it to 64 or 128 or so... After all, the AGP aperture is at the cost of mainmem. So if you set it to 256 mb, and the full aperture is used, that means the rest of the system will only have 256 mb (or less) to work with, which will probably not work out right.

Well, I'll be the devil's advocate here. I have 1 GB of PDP PC3200 RAM. I set my AGP aperture to 256, and I have a 6800 GT. I bought LOTR: Battle for Middle Earth and started playing it. After the 1GB of RAM upgrade, I expected my games to quit immediately and not have to sit there and flush the ram and refresh the desktop before I can do anything after I exit the game. The only way to do this is to CTRL ALT DEL and end the process. I looked at the game's mem usage...It was using 520 MB of RAM by itself. Granted, it's a very intensive game and is probably justified in using that much. That's over HALF of my phyiscal RAM. Add 256 to that and I have less than 256 left for all the other windows processess. When it got right down to it, I was using about 996 MB of RAM while running the game. I set my AGP aperture down to 128, have noticed no ill effects to gaming, and now it's a bit smoother transition from the game back to the Windows desktop. But, with MOHAA, COD: UO, and all my other games, I never had a problem with this after I upgraded to 1 GB. Granted, COD might be the best looking game I've ever seen use such a small amount of resources.
PS..I just got my Lian-Li PC-65B! it's great! Only complaint: Motherboard standoffs suck. They were too low, and I had to jack up my mobo to get the AGP and PCI cards to fit.
