Playing Vanguard SOH on an older system

[NoIdea]

Hi,

I ?m playing Vanguard and my game play is pretty choppy. I plan on building a new system come spring but till then I was wondering is adding another gig of RAM would make a large noticeable difference to my game play? Since I plan on building a new PC I don?t want to spend $100 for RAM that I will be only using for a couple of months, but if it will help a lot with my game play?..

Current System:

Intel Pentium 4 - 2.8GHz Northwood @ FSB 533 ?stock heatsink
