Help upgrading my nvidia gpu

I want to get myself a better gpu without breaking the bank, I have been looking at the, [h=1]EVGA GeForce GTX 750 Ti FTW DVI-I/HDMI/Display Port GDDR5 Graphics Card with ACX Cooling 02G-P4-3757-KR[/h]
My current pc specs are:
Geforce gt 730
AMD FX 6300
8 GB ram
500 watt Power supply

How do i go about upgrading this, is th gtx 750 compatible with my pc? and if so how do I change it?
Yes I am a noob when it comes to pc stuff I could use all the help I can get, Thanks in advance.

 

Download CPU-Z and put screenshots of every tag except caches and about.


A 750 TI (and every modern card) is compatible with your PC, the only issue could be if it is too big to fit in your Case. Changing the GPU is easy, (there are many explanations on internet).


Also, What is your PSU model? By the way the GTX 950 came out at the original price of the 750 TI and it is a card that performs way better.

 

My psu is ult-lsp550, 950 gtx huh looks sweet i'll get that one if i can

 

xD I forgot that now CPU-Z comes with a benchmark (You did not have to run it, but nvm) xD.

Everything seems alright, go with the 950.

Also, consider OC your CPU, you have a decent mobo for that.

 

Awesome im ordering now!!!! so stoked XD, Thanks man
