Going from a 955 to a 960T or 1090 is a waste of time and money. Overclock that thing. 1.5V is nothing for everyday use. If you have 1333 memory, unless you jump up to atleast 1866 is a waste too. That is if you can get the Phenom II memory controller to run stable at 1866.
Or get a AM3+ board and find a FX 6100 cheap and overclock the hell out of it.
