I think the second computer is overall better, the first has only 256 mb RAM, which is not good, the norm is 512 nowadays. However, the second comes without any OS installed on it, a bit of a problem, as windows is expensive (assuming you want that, linux is free and apparently better, ive never used it)
AS to whether they'll play battlefield 2, I've no idea whatsoever, look at the specs on the game packet/site and check those with the specs for those computers. i would imagine they'd work, as most games work even on my 3 year old desktop, try checking a gaming forum www.rgforums.com
