Would I need to upgrade everything if I upgrade my GPU Majorly?

Hey everybody... so I was curious if I needed to upgrade some stuff for my PC If I decide to buy a new GPU since mine is apparently "The bare minimum" which I kinda agree on sadly. I've seen some videos of people using my same CPU & The GPU I want but their CPU is overclocked largely... Would I need to do that? Would I need to upgrade my power supply? What would I need to do? Or would I be able to keep everything the same? P.S. I also plan on buying 4 more GB of ram (I currently have 4GB of ram so that would make 8)

My PC Specs
AMD FX 6300 (3.5GHZ, Using the cooling fan that came with it)
GTX 750ti EVGA (One fan, 2GB of VRAM)
4GB of corsaire ram or whatever
CS450M power supply from corsair

The GPU I plan on wanting to buy is a GTX 970
I mainly just buy GTAIV & some other games, though I plan on wanting to play GTAV, Arma 2 & 3 and some other high end games that my PC can't truly run at the moment.
Thanks, Jester

the asus card comes with a backplate, the evga card comes with a stiffing frame under the cooler that acts like a backplate

all gtx 970's are the same. the evga one just comes with a higher factory overclock then the asus one. For me I have always found that evga cards overclock better then the rest of them.

Back when I was young, dumb, and had money I went through 50 gtx 580s, I think newegg loved but hated me. I bought 1 580 and would stress test it for the highest overclock and then return it. I went through 10 cards from each manufacture EVGA, MSI, Asus, Gigabyte, and Zotac. On average Evga had a better overclock and a higher score in 3d mark11, Evga also has a great RMA program as well.

True... but I could care less about overclocking... I don't wanna overclock. Too much of a risk to what little I have or can risk in general. Plus I don't really care about it's score in something, just how good it can run my games I'd like to play and stuff. 😛 No offense.
