OK I am really confused now, and I mean VERY confused (I hope bifta can help with this

)
Just looking at the specs of the MX420, and accordingly the GPU runs at 250mhz, which mine does, but the memory of a MX420 is 166mhz, when mine is 333mhz?
Is this a OEM card since it was from my mates Dell Dimension 8200 or is it mixed with a 440 and 420? Or would looking at the GPU find what it is?
