hey guys...i think ur forgeting something
in most game cafe u see guys playing only UT2004 warcraft3,conter strike(1.6 or condition zero) And others like nfs u2 etc.there is no need to upgrade the comps after a year or so cause ppl r gonna continue playing these games and in case u get a profit of abt 60k like fresh season
said then u can upgrade once in 2 yrs
think about it mate!!!
p.s:there a lan center here in chennai called zap.that guy mints money like hell!!!
he's got about 3 centres with abt 30 comps each and 2 ps2 and 2 xboxs so u could do the same!!
