Will this gaming computer run the following games smoothly?

For Mafia II your system is inadequate . Your video card is an entry level model and Mafia II is a very demanding game. To run Mafia II on high settings at a high resolution you'll need at least GTX 470 (per the recommended system specs) and a quad core CPU.

Also the only way to get hardware accelerated physx in Mafia II is with an Nvidia video card, and not only that, but they recommend a you have a separate dedicated video card just for physx alone. Grid should run okay a mostly medium/high settings Dirt II recommends a quad core CPU and a 57xx series or better video card. So your computer will struggle with that PES 2011 should run decently for you.

High for Grid , Dirt 2 , PES 2011 medium for Mafia 2 Mafia 2 requires powerfull processor , other requires just nice graphic card and urs is good considering size of your monitor.

It looks to be a fine machine. However, the PSU is lacking at only 460 watts and the GPU is also lacking in that it uses the older standard of DDR rather than GDDR5. It may or may not play the games you have asked about on high or ultra but should still play them.

Plan on upgrading the PSU and GPU in the near future though because you won't be happy with the performance that the machine is capable of as it stands.

Check the game's minimum equipment requirements and compare to what you intend to buy. Pong, Freecell will work fine, I'm sure.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
