There has not yet been a side by side comparison for overclocking the i7's and Phenom II's on air. They have only tested it with LN2 and water cooling with the i7 coming out on top for the water cooling and Phenom II for the LN2. Because of this you can't really make your CPU decision based on overclocking.
If you are not going to be doing any stressful other than gaming then i would suggest to go down to a dual core and use the saved money to get a GTX 285. For the dual cores, Intel owns, so you will have to set aside your hatrid for Intel and get a Core 2 Duo.
