If you wait and buy one of those, I recommend going with the Phenom II X4 955 as the Phenom II X4 965 and 955 are the same CPU, and they don't really have an overclocking difference.
You're best off getting the 955 and overclocking it, saving yourself $20-30, it will give you the same performance as an overclocked 965.
Also, if you wait a couple weeks before you buy... The Phenom II X6's will be out by then, and their performance looks very promising.
And the heatsink/fan always come with "Retail" CPUs, but if they're OEM CPU's, they won't have a heatsink/fan with them.
Also, go with this 955 as it's the C3 stepping edition.
If you decide to wait a week.
