Thank you for Good article.

I have the following configuration of my PC (XP pro SP2)

Pentium 4 HT 2.4GHz
1.5GB RAM
160GB HDD

Currently it is taking huge time (approx. 35 mins for 2 mins AVCHD video). Can we improve the performance by adding a graphics card? if so, then:
Which graphics card is appropirate?
What could be the expected gain in performance?
