There's not much to upgrade to since you're stuck at a max of 95w. The highest is x4 3.0ghz. Only .4 higher than yours is not going to do much. You won't even notice a difference for your uses. The 910 is plenty of power and can handle a 6970; much higher than the 5670/6670 that I suggested you to upgrade to.

Just going to answer this from your other thread: x is representing a variable 945, 910, 925, 830, etc. You will also see on the hp page "TDP: 95watt" this is the max which is why the x4 965 does not work since it's 125w.
Thank you very much. So, in summary to your advice, a 945 or a 925 (95 watt only) would be an upgrade that my HP e9120y will handle. I do understand that there will not be much of a change with the 945 and probably none with the 925 but I may do it anyway because it will give me a chance to operate on my HP. Learn a little more. Haven't been able to find a 945, 95watt and I won't look for a 925, but could find the former somewhere in time.
Thank you again,
