Re: Need an AGP upgrade to a GeForce FX 5700 128 mb
to OP, been looking a bit for ya, nVidia dont have any agp versions of there 8xxx series and up. Couldnt even find a 7xxx series lowprofile agp.
If you had pci-e then a 8400 would be best i supose (dunno if 8500 is lowprofile, but it's the same gpu as 8400) I red in an article that the 8400 has some decent OC potential, but to get the most out of it you have to V-mod it and slap a big cooler on it.
So maybe you should build a new more future proof rig. Or perhaps buy a used one.
