Hello everybody, new to the whole computer building/gaming pc thing and am interested in not only having a good running pc that will last me awhile but also one i can play games on such as skyrim. So im thinking of buying a cyberpower ultra gua250 as its in my pricerange. Heard all good things besides graphics card. Whats the minimum graphics card i can get to upgrade to play games like skyrim and battlefield on good settings with this pc.
