New Graphics card

[TheBrum]

Hello i am brum and i am new here but i seem to be facing a problem at this moment i want to replace my graphics card i have right now but im not too sure if it would make such a big diffrence,

My pc build is this at the moment: http://i.imgur.com/hPzrrUg.png
I have been told it is an old computer so i already know that so far

My graphics card i have right now is a Sapphire Radeon HD 6670 DDR3

With that build i can play a game like Arma II Operation arrowhead with 25-35 Fps but since my computer is a quad core i found this a little strange so i started looking up things and found out the graphics card i have right now isnt the best.

But now the question is would i only need to get a new graphics card or would it be no use at all because of my processor
if it would be possible to make a big Fps increasement by buying a new graphics card i would like to hear if you have a graphics card reccomendation i would love to hear it since im not really good with computer themselves my budget is 100 euros

a better gpu will help. the newer gpu will do the newer version of directx. the issue with pre built pc is the low wattage power supply. you have to change your power supply. you may see a small bump in fps. then your old cpu going to limit the speed of the new gpu. if i was you I put some money aside for a new rig.

So if i would buy a Sapphire radeon 7770 will it be worth it to play games like Arma II, Garry's Mod and Battlefield 3 on low settings with a proper amount of FPS

you have to check the wattage of the power supply. newer card uses more power it can burn out your rig.
