Hello, actually have an i5 4460 with integrated HD4600, 8GB RAM corsair 1600mhz, asrock h97 pro4 motherboard and a corsair VS550W power supply. I found an used GTX 275 at second hand, looks like new, wasn't used for a long time. I can get it for 30$. Is that Zotac GTX 275 896mb 448 bit card better than HD 4600? Will it help me?
