DDR3 1600 compatibility issues? PSU watts? Cooling? Case?My 1st try...

Hello :hello: , and thank you for your time and help.

I'm preparing all the ingredients for my first self-built PC. No matter how much I read, there is always something new around the corner :o . But it looks like I'm getting somewhere. For starters, I'm keeping keyboard, mouse, monitor, printer, and speakers. I shall join the Dark Side again and use Windows 7 64 (but I'll install my own linux doubleboot after, I promise).

At the moment, my motherboard of choice for the project is Gigabyte GA X58A UD-5 coupled with an i7 950 processor. The GPU shifts between Radeon HD6870 and nVIDIA GTX470 (but looks like the latter: I got a good offer on Gigabyte's O.C. version). I'm not planning to go into SLI or Crossfire at the moment, perhaps next year. The HDD should be Western Digital Caviar Black 1 TB (maybe in the future, SSD for OS and a second HDD for space). I intend to get a BluRay reader/DVD reader-recorder, multicard reader, bluetooth connector (via USB, I guess).

Still in doubt about the case, I was thinking of Thermaltake V4 Black edition (plus 3 nox knik 12" fans, or something like that), ThTk V6 B.E., Thtk element G, or Thtk element S (always fond of this one); maybe NZXT Phantom (would it be a little large?, but then what a design!). Comments?

So, if there is room enough, why not use the Noctua NH-D14 (one of the best among the best, but LARGE), or the NH-C12P SE14 (to help cool places around CPU's socket). Advices on this choice?

About Power source, the point is how much do I really need? I know that with a 1000W everything'll be powered enough, but seriously... Remember the "Shrek" first film, when after rescuing princess Fiona they get back and get the first glance at Lord Farquaad's towering castle? I need something adequate for this platform, not something to compensate errr... Well, if you remember Donkey's speech, you get the picture. The thing is: 550, 600, 650, 700, 750 watts? Till I met GTX470 (specially Gigabyte's overclocks) 600W seemed more than enough. But with all its demands and CPU/case fans cooling... And also: if in 1-2 years time I try SLI, wich power supply?

And finally, I would like to use, with this CPU and MoBo, a DDR3 1600 memory kit, some 3x2GB adding up 6GB. Would you consider that enough for gaming? I haven't found a compatibility list or something like it, and I am, well, yes, afraid of making some stupid mistake on this. So if the DDR3 1600 is fine I would appreciate hints on volts (1.5 v, 1.65 v, 1.9 v are SO different, or even impossible to use with my intended build? Wich are acceptable?) and timings: CL9, CL8,... Please, try not to laugh too loud, I'm a real newbie but promise to do my best.

If you made it this far, your effort is greatly appreciated. This is my first thread and one of my first posts here and, being spanish, I hope you could get through understanding at least part of my needs... Help! and a very big THANK YOU.

  1. A good 750W PSU should be fine for both the HD 6870s or GTX 470s IF your planing to OC the CPU and GPUs latter on you might go to a 850W PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006 or http://www.newegg.com/Product/Product.aspx?Item=N82E16817139009

    For a HDD go for the samsung F3 1TB http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185

    Case CM-932 is a good deal ATM http://www.newegg.com/Product/Product.aspx?Item=N82E16811119160

    Ram http://www.newegg.com/Product/Product.aspx?Item=N82E16820145286 6 gigs is more then enough for gaming and light photoshop work.
