You can sort top by processtime (>), then it might highlight a 
particular bad performer.
Try also iotop, incase it higlights a particular app that is always 
writing to disk.

If you have an ageing processor, performing in cpu audio mixing via 
pulseaudio, can consume eg 30-40% cpu with 1 stream, more if you have 
two audio streams at once. It's something to think about.

The second one is non-accelerated video drivers, if you are doing any 3d 
work/effects etc.

For me, if you are browsing the web you migt use flask block/adblock to 
disable loading from certain sites. Some sites are unbelievable - 
multiple flash applets all appealing for attention...

Maybe you could start  runlevel 2 or 3 and see if there is much difference.
