Another issue that might contribute to some ui graphics problem is the indexing that os x does for a new system so that Spotlight Search will be snappy. That process uses a huge amount of CPU power for an hour or so when you first set up your system.

I believe Spotlight indexing only turns on when it senses idle. U maybe even configure it to index during powernap(?) only.
