MY PC is Intel(R) Pentium(R) Dual CPU E2180 2.00 Ghz with 2 GB RAM. Can I run FIFA 13 on my PC?
The answer lies more on the graphics card or integrated graphics (GPU). If you are using integrated graphics with the mentioned CPU, I wouldn't expect the game to look the greatest or perform well. If you are using a dedicated graphics card (not integrated into the motherboard), you may be able to play the game with higher visual settings and performance, though it depends on the graphics card model. We would need this information to be able to let you know how well the game may run.
The "can you run it" sites are helpful, but do not give the full information you may want or need, or may not be correctly stating whether a system can run a game or not. Here you can find a list of compatible graphics cards/integrated graphics that meet the minimum requirements: http://www.game-debate.com/games/index.php?g_id=3346&canMyGpuRunIt=Fifa%2013
Hovsep's link is excellent. Pick the game and you'll get an automated tool to tell you if your system can run it. Simple as that.
from the drop down menu select FIFA 13
