yea, 4.5 should be a breeze.
OC it and bench it.
Check your temps with Real temp and voltage with CPUZ
if you want to do some comparisons or need a good guide lokk here.
PS- when I overclocked mine I didnt go right to 4.5 I went up gradually (I followed Clunks guide)
Then I learned about offset voltages and am now running at +0.60 VCore which gives me 1.02 V at idle and 1.30 V at full load.(on air) So the benefits with that are obviously less stress on CPU and less heat all around
Hope this helps--
