yes, it doesn't need to be expensive.this neednt be overly expensive. Im no computer geek,but a basic graphics card is sufficient as long as it can support the number of monitors you want.I have a quad that I run on a 2.3 with 3gb ram. My broadband is 30. All works well.
like gamers, traders have been lured with the 'best' so they would shell out a lot more money.
