  1. http://www.anandtech.com/bench/Product/61?vs=288
    twice the CPU power
    As for the RAM, Not too much upgrade, most programs don't use 4GB of RAM
  2. Not much for gaming and more if you do heavy video editing/number crunching.
  3. If you are gaming I think you would have been more GPU limited than CPU limited.
  4. ok i see what you guys are saying. would i see a future improvement if i invested in a GTX 580 or something that is coming out soon?

    For gaming, yes, a GTX580 would be a big improvement.

    The other place where you would notice a big difference is with a SSD for the os and apps.
  6. I'm not sure if your PSU will be able to support a 580, can anyone else confirm or deny?
  7. The GTX580 needs a 600w psu with 42a on the 12v rails.
    If the kingwin psu is of good quality, it should suffice:
