hi guys i have a very big problem about building a new pc.I dont know what components to buy, do i need a entry or medium end level pc.I would be playing latest games and i want to be future efficient pc.Budget i saround 500$ but i can increase and decrease it (depend on what components i will buy). And what about second hand gpu or cpu?I am planing to buy those components:some low end i5 (3330p or 3350) or pentium(g3220 or g2030) and what socket is better for me lga1155 or 1150. And what about a 32nm athlon x4 740?fotr the gpu i found those:r7 260x . gtx 750 and a gtx 570 (570 is older but it is better i think) and some second hand r9 280 and hd 6970/7950.Also suggest me some mobos (100 $).Do i need 4 or 8 gb of ram and how many inches monitor do i need? Oh i forgott to say that i dont want overclocking! I am looking forward to your answers!
