I am looking to build a new gaming PC for main playing Mist of Pandaria, currently I have a lenovo Y470 laptop (I7 and GT 550M graphic card whish performed well for me in Cataclysm (lowest settings). I play lowest setting cuz I want more FPS, now with the new MOP expansion which is a lot more demanding that previous version I'd say, I plan to build a Desktop for it, not on budget but not looking for a real hardcore machine as well. Moderate one is good enough. ( >100 fps with fair settings, DX9 or DX11 doesn't matter. )
I will try to be more specific next time. this time I will chose Zared619's advice./ Thanks ALL
This isn't by any means a monster of a computer, but it should play basically all games on the highest settings. You didn't give us much information to go on, so if you fill out the build form, we can help you more effectively. For a preliminary build though, here it is.
