Is this an optimal Upgrade?

I have a Intel Inspiron 580 (don't ask, just please don't ask why I have it)i3

So I wanted to add a EVGA 560ti to it by upgrading it to a 600w power supply.

Can my mother board handle it?

Can I even upgrade it by changing the power supply?

If you can, tell me if I can upgrade the GPU to 560ti with full parts that I will be needing.

 

Thx for taking the time to read this :D

 

Looking at your motherboard on the dell website it shows you have a x16 pci e slot so the GTX560Ti should fit in there. If your buying the limited edition then you need to make sure it will fit in your case! I bought one and I had to squeeze it in there! Here is the website where I found your PC...hope its right. http://support.dell.com/support/edocs/systems/insp560mt/en/cs/cs_en.pdf
