So I have done a decent amount of studying on how to go about upgrading the g20 and I'm making this thread just make sure I fully understand what I have to do and get a few more questions I still have answered, hopefully.
My G20 has i7, 16gb ram and a gtx745.
I have 1 power supply that is labeled as 100-240v, what power supply, if any, would I need to buy to upgrade to a 980?
Having 2 DC inputs does this mean I run 2 power supplies at the same time?
I've read a lot about reference cards, can I only buy these and a explanation on what this is or a link to one would help alot
If I were to upgrade to a 970 or 960 would I still need another power supply
Finally is there anything else I should be worried about such as not fitting it in, overheating or anything of that nature.
Please feel free to ask for any information, I really need to upgrade from the 745 as it is horrible.
Thanks in advance.
