Right going into this kinda blind, so be gentle
a few years back i did buy a new PC ... my old one simply gave up and i went to the first store that was open and did buy whatever they had... yes it was a mistake.
what i ended up with was a machine with :
I7-4770 3.4Ghz
GTX-650
no clue about motherboard or how i find out what it is ..... or what power supply
now it runs .. but not very well tbh. and i figure that the weakest link in this junk of a PC is the GPU so i am looking into upgrading that as buying a new PC is not a option atm.
So have looked around and the best upgrade seems to be a Asus GeForce GTX960 4GB or a Asus GeForce GTX970 4GB both are within my price range.
I have limited experience in pulling things out of a computer, replaced a hard disk once and stuffed in some RAM but that was like 10 years ago, and pretty sure i only made it work due to blind luck.
So to the questions
1) what are the odds that a new GFX card will actually fit the motherboard ?
2) And if it should fit how much of a hassle is it to do the swap ? did some google search and seen several youtube videos by now and they are pretty much all like *LOL easy shit, but you might want to fiddle with x file and do y in BIOS* now .. that i really don't want to mess with ......
3) how big is the actual difference between the 960 card and the 970 ? the last cost around 100$ more here ( Denmark ) and if the difference is something like * you can have shadows on high instead of medium* i do not need that
Thanks in advance.
