I'm about to buy my new baby and just wanted to run the components past people to double check the compatibility.
Processor: Intel CPU i7 875K OC Quad Core Processor
Mobo: Gigabyte GA-P55A-UD7
Graphics: Asus NVIDIA GTX 480
Hard Drive: 120GB SSD OCZ Technology Vertex 2 Solid State Drive
Case: Coolermaster case Cosmos 1000
PSU: Coolermaster 1000 W Silent Pro Gold
RAM: G-Skill 4GB Ripjaws DDR3 PC12800-1600Mhz Cas7 Kit
I haven't shopped around for the best price yet, but those components there come to around £1350.00 (about $2000). I also plan on adding a cheap DVD drive and network card, which shouldn't add more than another £50. I have an external USB 2.5" HDD which i'll be using for storing data.
Is there anything that I look like I have missed?
I'm planning on going with the stock heat sink / fans etc. as I don't plan to overclock for a few years, when I'll also probably buy a 2nd GTX 480 - hence the hi spec mobo and PSU.
the GTX480 is really not a good value for the performance. In fact, 2 GTX460s in SLI give MUCH better performance, and at less cost, than 1 GTX480. Of course, this requires you to have an SLI ready motherboard, which that one that you have picked out is.
Other than that, everything should be fine, though I don't know if you really need 1000W for the configuration that you have, unless you're planning on SLIing in the future with 2x gtx480s...in which case, I think you actually will need MORE power than 1000W...as 2 gtx480s are power hogs like you've never seen before.
