Which of these gaming computers would be a better buy for money?

The better one that is here is plan "A". The hardware that is installed on this unit will hold up to the abuse that intensive graphical games can give it. Biggest low point of both of the units is anything that says Vista on it. Not a Vista person and have been in the it field for 14 years. Rather use DOS than Vista. But personally I run XP SP3 with less problems than the most up to date Vista. Beta testing Windows 7 right now and am seeing a lot of Vista like traits in it which means that the public will again not like it, toooo security intensive
