My compaq 5310F works better than any I have owned. It don't freeze up or lag like most I have had. I bought my computer too replace my other compaq which was out of date. I run windows vista which I really was lost at first was totally different from windows xp. The control panel was easy too find but some other things was not. Called tech support was very helpful. The ram is great can add another 1000 ram stick. I am not a smart computer user am learning new things everyday. I have had this compaq for 2 years now and still have plenty of room on the hard drive. I play games and download pictures and files but don't download music. Think music and videos slows any computer down. My husband has a dell computer it is so slow will not play games on it. His computer freezes up all the time. I will buy another compaq when this one gives out on me in the future. I would recommend compaq computers over any other from my experiences. The video card is great graphics are perfect.
