^^This is my Windows Experience Index. "Desktop Graphics Performance" score is only 4.3 while other scores are good.
I have i3 3210 procssor, Intel DH61HO Motherboard, Zotac GT 610 2GB graphics card. My PC is now about 2 yrs old I'm thinking to upgrade it. Can I improve Windows Experience Index & performance by upgrading only my graphics card? If yes suggest me a new graphics card.
