    Yes, AGP graphics cards in most cases will outperform PCI graphics cards.

    Choose the best one qualitatively+specifications wise, if you want opinion on some specific solution, please provide the list of available options. I'm sure you'll get the best possible advice you'll need from this lot here (ref. DBZ). :)

    pci-e > agp > pci

    PCI (32bit bus ,33MHz clock) = Peak transfer rate up to 133Mb/sec (32bit x 33MHz / 8bits/byte)
    AGP-1x (32bit ,66MHz clock)= Peak transfer rate up to 266Mb/sec
    AGP-2x (32bit ,66MHz clock-double pumped)=Peak transfer rate 533Mb/sec
    AGP-4x (32bit ,66MHz clock-quad pumped)= Peak transfer rate 1066Mb/sec
    AGP-8x (32bit ,66MHz clock-8 strobes per clock) =Peak transfer rate 2133Mb/sec
    PCI-E x1 = 256Mb/sec upload/download (512Mb/sec combined)
    PCI-E x4 = 1Gb/sec upload/download (2Gb/sec combined)
    PCI-E x8 (v1.x) = 2GB/sec upload/download (4Gb/sec combined)
    PCI-E x8 (v2.0)= 4Gb/sec upload/download (8Gb/sec combined)
    PCI-E x16 (v1.x)= 4Gb/sec upload/download (8Gb/sec combined)
    PCI-E x16 (v2.0)= 8GB/sec upload/download (16Gb/sec combined)
