Hi, Am due to order a new base unit to replace my old one, however I am looking for a recommended graphics card specifically to play ArmA2. Can anyone advise? Any tips? I'm on a budget - can't really afford to pay more than around £100 uk sterling for a graphics card. I've previously always used an Nvidia gaming card - so would prefer to stick with Nvidia - just not too sure what to go for. New system will be Dell Vostro 420 - have gone a 2.6 quad cpu with 4gb memory, have opted to go for a basic card then get a decent graphics card from a local reseller - as they are cheaper, usually used ccl nr leeds as they do a good range. Anyone suggest anything? - don't normally do much gaming these days - loved the old flashpoint - did all three campaigns and they are memorable. Played Armed Assault last year and had to get a new pc to play the new game!
