I really want a new computer...I have a 5 year old laptop which still works perfectly but it has been years since it could play modern games. I like first person shooters and I like the keyboard and mouse inputs much better than any controller on a gaming system. I am thinking of buying the base Mac pro with the quad core processor...I have get 0% financing for 12 months which is pretty darn appealing. I am I crazy? I got 5 years (still going perfectly fine) out of my laptop...how much usability can I expect to get out of a Mac Pro? I also know they retain there value pretty well too. My father has a 27" iMac which is beautiful but the graphics card is not upgradable which makes the Mac Pro more appealing.
