What do you think of my new PC?

Hey Maestro. For 9+ year old games, you're probably fine even without a graphics card.

For comparison, a friend of mine picked up this windows tablet while it was on sale for his young son for Christmas as a way to play some older PC games, and more recent indi games.  

(For reference, the lad is about 7 and has been playing mostly on the family's Xbox 360, as well as the his father's DS and a lot of older emulated console games on his father's PSP.  He's been wanting to play Minecraft on his dad's gaming PC for while, due to more mods being available.)

So that little Windows 10 tablet had no graphics cards, and is outclassed by your new machine in every way, yet it still runs a lot of older games, and indi games just fine (including Minecraft, but it isn't exactly system-intensive), as my friend has been installing and testing games so it is ready to go for Christmas. For what you're doing, I'm sure this PC will work out just fine, even without a graphics card.

Cervantes Thank you guys for the input. I'm really relieved to know that this computer will run the games that I planned on playing.

Now about Windows 7, is it easy to use? Are there any things I should know about it that anyone here has experienced problems with?

Ok thanks!

We're waiting, Cervantes. And we'd like an answer.

By the way, Crysis is a really fun game. Some people dismissed it at the time by saying it was just a tech demo, but it's not: there's great gameplay to support those graphics.

But there's one important recommendation, though: the game is only good if you choose the "Delta" dificulty. Some people thought it was a harder dificulty; it's not. It's supposed to be a more realistic one, so you die in fewer hits - but also do the enemies. The Korean dialogue isn't translated, the health regenerates much slower, there are fewer HUD elements and, most importantly, the AI is much better in this mode. As a simple example, if you turn invisible in front of enemies on normal, they'll immediatelly lose you; on Delta, they'll spray some shots towards the location you were last seen and will investigate the surroundings. It was while playing on this dificulty that I realized how much fun the game was, since I had to think about how I would approach each base (it actually reminds me of the gameplay in The Phantom Pain); I don't know why they didn't choose Delta as the standard dificulty, it made the game so much better.
