the arma2 devs use 8core workstation systems!
a 8 core and a 5870 2GBvram is the 'minimum' for arma2.
the us army use arma2 to and they use 8core workstations to!
arma2 uses cores like this: 1 core graphic 1 core streaming data (because the running game is uncompresset more than 20gb) 1core is physic 1core is networkstuff an the rest is for AI (you need a lot for highskilled AI)
surprime comander in a patched version can also use 12 core if you wana play with 50 000 troops many many AI to calculate!
'ARMA3 will be dx11 means real multicore graphic engine'
why i sould buy a computer for OFP1 (singlecore) ?
i buy a computer for arma2/arma3/surpime comander or a raytracing based game!
i still do not play ps3/xbox360 ports on the pc! this loser games sould DIE!
