Conclusion
Buying a good performance video card will reap many benefits - you'll be able to play the latest 3D games in full screen glory, as well as edit video and graphics with ease.

However, please take note that having a good video card does not necessarily translate to great video performance. Factors like your CPU, motherboard and system RAM will come into play. For example, having a BFG GeForce 7800 GTX installed in a old AMD Duron or Intel Pentium Celeron system will definitely not give you the desired video performance you seek.

Now go do some research and buy that dream video card
