Im not a full on gamer just in my spare time hope this helps firstly AGP graphics cards are slowly being phased out and the new format has become PCI which is the slot and connection by which the card is inseted into your motherboard. There are different AGP formats 4x or 8x the later being the most recent before PCI came onto the market so if you decide to buy a new AGP graphics card remember to check the AGP format of the model you choose looking at your post a AGP8x.
Intergrated graphics is the graphics controller that is intergrated into your motherboard generally these graphic chipsets are inadequate to play games well on because they dont have enough grunt to produce enough frame rates for game veiwing and playing.
A dedicated graphics card such in the AGP or PCI format will perform much better giveing you many more frame rates and games will not only run smoother but be more pleasing to the eye, Seeing your motherboard only supports AGP you are limited to these cards.
The chipset is one of the most important factors as well as the ram the card has when buying a graphics card to of the major producers are ATI and NIVIDIA you can still buy decent AGP graphics cards the best bang for your buck at the moment on the budjet market are those cards with the 6600GT or 6600 chipsets not knowing your budget you can pick them up for around $230-50 AU an example of a graphics card- 128MB Leadtek winfast 6600GT AGP8x graphics card
This is for all of you heavy video users(Gamers, Video editors) out there. My system works very well at 3.0Ghz HT,1.0GB ram, 250G hardrive. I have an D865GBF Intel motherboard, and this motherboard will only take an add on AGP 8.0X video card. I recently had a problem with my add on ATI video card, and I now need to replace it. My question for all of you is that it seems the market is turning to PCI Express X16? I enjoy playing several video games, and now that my AGP card is toast, I am forced to use the integrated Intel Extreme card.(NO FUN) I would like to buy the BEST AGP 8X out there, but I do not want to spend the money on a new AGP card, if I would be better off with a new motherboard with the PCIX16 graphics support? Is there really an advantage to the PCIX16 vs an AGPX8? Either way, please let me know what the best Graphics card is, based on what you have seen?
