just upgraded from a p4 2.4ghz northwood to a 3.4ghz northwood. currently have a 9800pro 128mb. is it worth the 300 dollars to upgrade to a x800XL ? or should i just keep the 9800 pro. i don't have pci-e so that's not an option. i searched but am not sure if the 3.4ghz cpu will max out the 9800 pro
