Hello, my dad's computer died recently and he needs a new one. The only things this computer needs to do is surf the web, check e-mail, and play Starcraft 2. I would like him to be able to play with decent graphics settings. His budget is flexible but approximately $650 with a monitor. Here is a link to SC2 recommended specs http://us.blizzard.com/support/article.xml?locale=en_US&articleId=26242 , not sure what kinda of graphics performance those would yield. He needs a computer as soon as possible for his work, so ideally I would like to get a store bought. The problem with those is that none have graphics cards within the price range. Is it ok to buy a computer such as a Dell, or Gateway with decent specs and then add a graphics card? For example, how well off would I be buying http://www.bestbuy.com/site/Dell+-+Inspiron+Desktop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor/9698836.p?id=1218153428400&skuId=9698836 then adding http://www.newegg.com/Product/Product.aspx?Item=N82E16814150472 . Any advice/info will be greatly appreciated.
