Hi people, As I am getting Tradestation, I don't know whether to add GIG or just get a new computer. I can buy 4 gig of Ram. I presently have 1 gig. Tradestation says that 1 gig of RAM is fine, but EVERYONE I spoke to said you need at least 4 gig. I have a Dell Dimension 9150 (2 years old) Windows XP Professional I have Intel Pentium D 820 (2 8 GHZ) w/ dual core technology. 1 GB Secure digital card Monitor 1280X1024 resolution Video card 256 mb ATI hyper memory PCI-Express X16 Do you think that I should get a new computer or just add RAM. Thank you, Torontoman
