Depends on your motherboard, ASUS boards you go into bios, under cpu extras or some such thing, it is known as core unlocker, it will work or not, you can tell by the bios/cpu-z now calling your chip something else other then 960T, the unfortunate side is, you usually lose a chunk of OC headroom in the process.
For a single gpu, the 955BE and 960T are about the same, I have 0 issues feeding my 6870 overclocked, and when I do OC the chip, my card runs like a ferrari :P
So as far as bottleneck, I doubt it, you want you chip to feed the system as best it can, up the cpu/nb speed.
best calculation to use for this is.
base memory speed x3=cpu/nb desired speed.
example
ddr3 1600 base speed=800 800x3=2400 so you want the lowest speed for cpu/nb or memory controller aka IMC to be 2400mhz.
Though do be sure to leave the HT speed as close to stock as possible, mine is 2000Mhz on the HT, no matter how far I overclock, the performance benefits for having HT up there is not worth it, and can actually hurt it performance/stability.
So fast cpu base speed, fast cpu/nb, fast memory at good timings, fast gpu clocks, default HT speed.
Also ddr3 1600 at looser timings i.e 9,9,9,24 is generally better then 1333 at 7,7,7,21 extra bandwidth is better then tighter timings in virtually everything, especially when doing memory intensive tasks, but, loose timings high speed, say ddr3 1600 at 10,10,10,24 well then the tables flip again :O
If you have option in bios, make sure memory is set to unganged mode as well, sometimes known as DC mode.
Your chip if you decide to do so, should be able to overclock to 3.8-4.2Ghz with decent voltages, decent temperatures, with a decent cooler, that will make sure it flies :)
