Greeting from newbie and hardware question

[lightson]

Greetings T2W folks, have been swing trading stocks on and off since 2006 but getting more serious/frequent, just joined the forum for more info/opinions.

I plan to buy a new computer to run NinjaTrader, initially for realtime scanning of abt 100 stocks for my buy/sell signals then shoot a text to my phone. Is an i3 with 6gig memory plenty or should I get more power?

Thanks for any advice you wish to share.
