My dell inspiron has a i3-2120, i put in a 750ti and a 500w power supply when i bought a new hdd, seagate barracuda 1tb. My main question is what can i upgrade in my pc without rebuilding the whole thing, i dont think a new processor is a option yet because i think they soldered in my i3 so i can't change it. Could i get a better graphics card? such as a 970 or something higher tier? would that bottleneck hard? games like h1z1 to get more frames? i dont know what to do
