My 2011 17" Macbook pro is doing the same kinds of things but in 1" squares.
Known problem with the Macbook Pros but Apple won't acknowledge the problem. They just keep replacing mother boards that fail again.
Which OS are you running? I suspect in Mavericks Apple cranked down the processor performance to cut back on heat issues in the MBP. I have two early 2011 MBPs, one a 15", the other a 17". I use both for Folding@home which will peg the processors. The 15" runs Mountain Lion, the 17" runs Mavericks. The 15" runs very hot, the 17" runs much cooler (both to the touch at the top center above the keyboard.)
10.8.5 No Mavericks for me. Sticking with the Cats. When it freezes it gives a loud 3 beeps repeated. Normally means a memory probably.Top temps for the processor are about 160
Do a search for 2011MacBook Pro freeze. On the Apple community there is a 150 page thread for the 17" alone
Here is a 295 page discussion on the 2011 discrete video card2011 Macbook Pro and discrete graphics card
