I bought my PC in pieces, and before I got the graphics card I had the computer built and running with integrated graphics (i7 4790k with 4600 hd graphics) I was actually pretty impressed with how well it performs. Without overclocking, I could play dragon age inquistion on a mix of medium/low settings on 1080p very well. Arma 2 and Dayz I could run a mix of mostly medium and some high settings, comfortably, and in 1080p as well. To be fair, I could NOT play Witcher 2 in 1080p even on lowest settings. The integrated graphics aren't as bad as people make them out to be...Not saying a dedicated graphics card isn't significantly better and isn't worth the investment, just pointing out that integrated graphics aren't all horrible, especially the 4600. (My system was also using 2x8gb [16gb total] at 1600, and that can also affect performance while using integrated graphics. Also, all of the games were installed onto a SSD.)
