Have you got a higher resolution copy of that Dark Angel? Or at least one with a little less JPG compression? The detail seems lost due to compression in that pic...
gpdesigner - Martocticvs took the words right out of my mouth. If your cursor is slowing down and you're having problems typing, it's got little to nothing to do with the site unless you're having issues with the flash banner. But you'd definitely be having issues with out sites using flash (an extremely high percentage of major sites these days) if that was the case.
