tou can "softmod" a 9800Pro to a XT. If your 9800pro is a sapphire, it is easy....first of all, look at your PN number on the board of your card. It should read: XXX-XX7500-XX-XX or XXX-XX8800-XX-XX. The your numbers will be different (hence the X's), but it should read in the 7500's (mine is 7533), you can not softmod it
. If it is in the 8800's, you can. If this number is on there, thing you can download the bios for the 9800xt and flash your card to that bios...(search the forums for a good explaination). If you are unsure of the number, you can look under your heatsink....a 350 means no softmod, a 360 means go for it. It is hit and miss as to weather you have it, but most newer cards have it, just depends on how long your card was sitting in stock before you bought it. Good Luck!!
