Thanks and sorry about my terrible english:

Hi all! I just bought a Top PC, too expensive  :( I know people here will start bashing me for that, but I wanted all that just because some features of the motherboard, gamming and a add to my music studio...

I used to play in a Athlon XP4000 939 (not x2..), x800xt allin wonders... 6 years with that machine... now I got this i7 860 + ati XFX 5870 1gbddr5, font xfx650w, ASROCK P55 Deluxe3 LGA1156 .. plus V8 cooler.. I am searching for a good case and good monitor..

Why I need help... I wanna taste the fury of this system... what games do you recommend.

I already have: Quake Wars, Flight Simulator X, Fallout 3 (play on my note)... 

What should I buy?

Other minor questions: Monitor: 5ms or 2ms? makes diference?

Dragon Age or Crysis. Depends on the game genres that you like.

try Crysis. rare to find a pc with enough muscle to play it at full 100% specs.

well if you just want to see what your rig can do obviously Crysis would be the way to go but I can reccomend Metro 2033 it has it's flaws but still a good game + it's DX11 lol same for S.T.A.L.K.E.R: call of pripyat other than that just read some reviews and watch some gameplay on youtube and buy what you like

Some old ones in the list too:

Crysis
Mass Effect 1 & 2
Dragon Age
Metro 2033
Empire & Napoleon Total War
The Witcher
Dawn of War II
Supreme Commander I & II
Left 4 Dead 2
Orange Box
Oblivion
Neverwinter Nights 2

In terms of best graphics, Crysis. If you want to do something with your computing muscle other than pure eye candy, then I recommend Mount and Blade. It's an rpg typa game where you command the general of an army, in battles you control your own character and give orders to the soldiers - very fun

The main game limits you to about 150 people on screen at once, but you can get a mod that expands this limit to 10 000. Medieval warfare including awesome seiges and cavalry charges with 5000 soldiers a side!

Humm, Crisis, Metro 2033, Mass Effect 2.. and about a game from HALO or GoW?

Mount and blade I will get a better look at it.. ;)

thanks :) I accept more obs and recommendations :)

Left 4 Dead 2 is only $20 on Steam, and comes with free DLC. Get it.

No, definitley not.

Obviously you should try Crysis to see how good it can look; also, it's not a bad game, I liked it very much except for story. Some S.T.A.L.K.E.R. game could also work. Personally I also recommend Titan Quest even though it's not that new - it's a very enjoyable Diablo clone.

Supreme Commander? Sins of a Solar Empire? Civilization IV, definitely. Half-Life 2 and its Episodes? Dragon Age: Origins? Company of Heroes? A free turn-based strategy game, Battle for Wesnoth is good, doesn't require a powerful computer (but a great game to try anyway). Deus Ex (old but still worth a try)? Far Cry? Total War series?
