Hi,

Your not the first person to try this. On new dell models, you have the option of opting for a go6600 or a crappy tappy solution. So, my client purchased a seperate 6600 found on ebay and brought it to me to install. It was simplay a matter of discontecting the power and another cable and then pull the board out carefully...then insert the new vid card and plug in properly. I cant remember which model, but you can even install a 6800 and just flash your bios.

For your model, I think you will need the bios from a 2600 model thatcarries the gforce card and then flash your bios with it. I wouldnt recommend going any higher even if you do find a card that fits. Heat becomes a great issue then.
