I admit I am not an expert on mobile GPU's but apearently the 945 chipset has a "Intel GMA X3100" graphics-chip. And according to (google and) a test from 2007 is was 40% worse then Radeon X1300 or Geforce Go 7300.
Both are not exactly what I would call good graphic-cards and neither are up to date.
So either I misread that and misunderstood that, or you despearalty nee a new grapic solution for that notebook. On what to get I would suggest to wait until someone with experience in that field answers here.
