i've waited for some time now to build a new system, for the general purprose of playinng CoD modern warfare 2, along with SC 2... and here is my layout so far. i am still new to this so i would appreciate open critism and suggestions.
Case : contemplating between CM storm sniper AND CM Cosmos1000 suggestions and other recommendation are more then welcome
Motherboard: Asus P6T delux
PSU: i am not 100% sure what kind of power wattage i need to complement this system
GFX: Sapp/HIS ATI HD5870 1GB GDDR5
Ram: i am very uncertain what would run well with this system (aiming 6Gb DDR minimum)
CPU cooler: Xigmatic Dark knight.
OC: i dont intend to
SLI: later in the future i intend to run x2 HD5870 in Crossfire.
reusing: running dual 24" asus V246H HD monitor
keyboard and mouse
DVD optical drive
and my 1x WD 250Gb 7200RPM and 2x Seagate 1.5Tb 7200RPM HDD
i thank you all for your inputs and suggestions. =D
Regarding the case:
I currently own a CM Cosmos 1000, and I admit that the thing is a beautiful beast! However, I knew ahead of time that it would require some modification in order to improve the airflow. With that in mind, you might want to steer clear of the Cosmos 1000 if you are not up for modding the thing.
If you're looking for a great case right out of the box, I'd go with the Antec 1200. Also, if you're willing to spend more on a fantastic case, check out the Corsair 800D.
I would go with a high-quality PSU such as Corsair's 750W model, given your desire to run Crossfire. If memory serves me correctly, ATI recommends at least 500W for a single 5870, while 700+ is needed for Crossfire. Whatever you do, do NOT skimp on the PSU. You want something that is high-quality such as Corsair, PC Power&Cooling, etc.
Regarding the RAM: There are plenty of options. In general, look for kits that offer lower timing values. Here are some options that might be worth considering.
