If you are looking to seriously improve the WEI scores by upgrading your hardware, get a middle-higher class graphic card, an i5 or i7 processor, larger amount of quality RAM and most importantly a decent solid state drive. Since the general WEI scores will reflect only the lowest scores among the 5 components, hard drive performance will usually be the key to bring up the score. A solid state drive will give you a huge boost to your WEI scores as all the classic old drives, even those spinning at 7200rpm will not be able to break score 5.0.
