Hi im considering between buying a pci express x16 graphics card and a agp 4x/8x. I would like to know which of these would be better and also if my computer is compatible, i have an agp and a pci port but i do not know if its too old. Anyways both cards have 128mbs. THe pci has a memory clock of 550mhz while the other has 400mhz. The ramdac of both is 400mhz. The pci also has a loud fan that the other doesn't have a fan. THe core clock of the pci is 300mhz while that of the agp is 250mhz. The main purpose of the card i need is to connect is to use the s-video out on my t.v.
