After I read http://www.tomshardware.com/reviews/intel-core-i5,2410.html my thoughts are you may want to find an i5 based system and then pick a video card from this list -> http://www.tomshardware.com/reviews/best-graphics-card,2404.html
It would be hard to do better than that.
i need help. My pc is 7 years old =) And now I want to create a new PC. But I dont know what is important.
I need high quality propsitions (to playing games) for a new pc.
Thx for the help.
