I have attempted unlocking the cores on that 960t several times. Always does the same thing. Pixalated screen then lock out. I always have to go back into the BIOS and reset everything. I just left it as is, used the overclocking software, its running at 3.8 right now. Added an SSD. Gave it to the wife.
Have been using my laptop as a desktop (attached to wireless keyboard and mouse and 32 inch monitor). Just wanted to free up the laptop.
Instead I went ahead and purchased an HP Laptop last night, a Pavilion m7-1015dx Entertainment Laptop. So for now the other laptop will remain as my desktop while I build my new Desktop.
Think I will go with an Intel Processor.
As for what it will be used for. Video and Photo editing, Office Doc's (Primarily big spreadsheets). and basically web use (maintaining my vBulletin Gun Forum, updating websites, that sort of thing).
Honestly, I just want to get as much power out of it as cost effectively as possible...just because.
