iK1DDER :
I spent almost 900 dollars on my pc build and it still isnt great for gaming. i run skyrim at 20 fps in heavily snowy areas and when the weather is clear, it is around 26-40 fps. My specs are: MOTHERBOARD: Gigabyte ga-z97-hd3, POWER SUPPLY: EVGA 430 watt 80+ atx, PROCESSOR: i5 4690k 3.5 ghz but overclocked at 4.24 ghz right now (but i could overclock higher but choose not to), HARD DRIVE: Western Digital 2TB 3.5-inch, SATA 6 Gb/s, 7200 RPM, 64MB Cache WD2003FZEX, RAM: G.Skill 2 x 8(16gb) DDR3-1600 PC3-12800, GRAPHICS CARD: NVIDIA GeForce GT 730 1GB, Windows 8.1 and i use an external usb optical drive if that matters, which is: Lite-On IT Corporation Optical Drives EBAU108-01
Let me tell you a quick story of how important it is to have a good GPU.
A few years back, I purchased myself a new desktop computer. It was about $400 and it performed spectacular for heavy schoolwork and business. It's specs were i3-3240, 4 GB of RAM, and integrated graphics. So it is a lower end power computer. But it worked just beautiful for me.
However, I noticed that I couldn't play games very well. Skyrim, for example, had to run on low settings and I still experienced lag in areas like the dungeons.
After reading around, I decided to add a dedicated graphics card.(At this point I upgraded RAM to 8 GB). After a while of researching, I came across the Geforce GTX 750Ti Superclocked 2 GB. It had extremely positive reviews and was small in size. So I ordered myself one and installed it on my computer(along with upgrading the psu). When I first started up Skyrim, the game switched the settings from low to Ultra High. Just like that. I could play Skyrim on ultra high and there was no lag whatsoever. So games I played on this computer now either had the settings on Very High or High(including Dragon Age Inquistion)
So I just created a mid-level gaming computer that costed me in total $600.
The graphics card you bought is cheap and much older. It is not designed to be powerful. So you have a bad case of bottlenecking. You should at least get a GTX 750Ti. But if you already spent $900, then go higher! Get yourself a GTX 970 or R9 290 Tri-X or 390. The graphics card should be one of the most expensive components on your computer.
Do NOT use the integrated graphics. Integrated graphics will always fall behind a dedicated graphics card. You'll get even worse performance. You already spent that much money, get some more to get yourself a more powerful graphics card. Otherwise that's $900 more or less wasted.
Good luck!
