I think that Intel 845GE series is still out there in the market. U may hv 2 go 4 an xtensive search. My earlier Mobo was a Intel Original 845GEBV2 witha 1.6 Ghz pro. But Tht features a 4X AGP slot and will slow down a 8X AGP GFX card. I suggest u to go for any mordern board witha new processor. That will be good if u r planning 2 buy a new GFX card.
Its better dude to go in for a new motherboard from Intel (D865 or above) or a AMD motherboard and also spend sum money on a decent AGP card like the nVIDIA Ge Force FX 5200 graphics card....
