Amazingly a card exhists that has a new gpu but utilizes the good old 33mhz pci bus. Read how it performs here

Hmm it uses the RV510 VPU with DirectX 9.0c, OpenGL 2.,0 * FSAA & HDR possibillities , though the HDR setting would be far too much asked for a X1300 PCI hehe.

It´s only a very bad comparrison test they gave on 3 different cards 3 total different resolutions + settings they gave the X1300 PCI low settings while the GeForce 7300GS ran on medium settings and the 7600 gs on high settings, not a fair comparrision test to be honest.

To make it a fair test use on all three the same reso + settings then roll out conclusions.

here are fairer results. or shall I say very sad results. The card is currently the slowest pci card available on the market

..there are some cards for pci that should deliver better performance-nv is going to make a gf8500gt card for pci:
