I recently traded my 9800gtx+ OC for the HD 4870 today and i was told i would be amazed at the diffrence. so i installed everything and updated the drivers and wouldnt u know it, no diffrence from the nvidia card. it almost seems like its not running as well as the nvidia. i ran the auto tune in the catalyst program which oc'd it a little. Anyone using this card that has the settings perfected? im new to ati so im still not familar with everything...been an nvidia fanboi for awhile.
