hey guys, this is my first build ever and I was looking for advice and/or opinions, hell, i'm not even 100% sure if these parts are compatible with each other, (100% noob).
MoBo: Intel Extreme Series DP67BG
Ram Memory: Corsair Vengeance 16Gb 2x8Gb 1600MHz
GPU: GeForce GTX 650, maybe the 660
Hard Drives: Western Digital Caviar Green 3Tb, 64Mb Cache
haven't decided on an SSD for the OS yet...suggestions?
PSU: Suggestions? Not sure what size I need.
OS: Windows 7, maybe windows 8, depends on how long it takes me to build my machine.
Case: Cougar Challenger, if I can't get the orange one i'll probably go with the aerocool syclone II
Like I said earlier, this is my first build and i'm a newbie, i've done a little research but I still don't know how to figure out how much power i'm going to need for the PSU, and i'm still a little confused about the GPU too, should I spend the extra money to get the superclocked 2Gb card? And whould it be better to get 2 650's or one 660 for about the same price? I'm sorry if any of this is confusing, but i'm a noob.
Edit: I would really like some suggestions on a GPU that is compatible with my MoBo, and is in the ballpark of $200-$250
