I wouldn't consider upgrading the CPU (if that's even possible). The speed bump will be minor, and the laptop is no longer worth much. The only upgrade I would consider is a solid state drive you haven't done so.
I have an older, but VERY dependable Lenovo thinkpad T410 which I've upgraded to Win 10 Pro, along with Office 2016. For a well built business laptop, although it's an older machine (2011), it has, and continues to outperform all previous, and other current laptops I have. I'm just not very savvy about CPU's, and am wondering if I should replace my Intel core i5-520M 2.40 GHz processor with either the Intel core i5-540M 2.53 GHz (about $50), or the Intel core i5 2520M 2.5 GHz (about $125). Does anyone have any thoughts on this? My ram is fine at 8Gb, and I'm curious if by upgrading my CPU will make a noticeable enough difference. Any feedback would be much appreciated!
Oh makes sense haha
they don't they just have a database of most cpu's and have a page made for just about every match-up, this whole website was basically made by a machine.
why would you compare these?
