I've been saving for awhile and can now start a build from scratch. I have about a $1600 budget give or take 100 depending on performance advantages/disadvantages. I have this build in mind so far...all from newegg:
^ You are overspending on many components...
1. PSU - Why do you need 1200W PSU ? Are you going to run 4 of those cards in SLI ?
I would suggest you this PSU -
Antec CP 850 - It has enough power for 2 of those cards in SLI and is compatible with that case...
Antec 1200 + CP 850 http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
If you want to shave off about $70 and get a different case, I'd suggest the Cooler Master Haf 922. Great ventilation, nice and spacious, and cable management make it a close rival of the 1200. If you want to change the color of the LED's to blue (if that's why you chose the 1200), just get two of these:
Case / PSU - You can be arrested for buying the Antec 1200 case and not putting the Antec CP-850 in it. Ok, I'm kidding but "there oughta be a law" ! You simply can't find a quieter PSU and topping it electrically (i.e. SG-850) would cost double. Until 2 days ago, PSU was $109 at newegg....mwave has for $118.
here's a review of the BFG EX series (7.0 performance rating) and the CP-850 (10.0 performance rating)
MoBo - Gotta lean toward the Asus P6X58D with SATA II and USB 3. yeah it's a $100+ more money but what you're getting in future compatibility and quality is worth it.....besides, the cost is just about offset with the money you're saving on the PSU.
HD - Check out the performance charts and pick whatever 500 GB per platter drive performs best under your usage patterns. The WD Black 2 TB is a good choice but at smaller capacities, you are limited to the Seagate 7200.12 or the Spinpoint F3. The 7200.12 excels in gaming, multimedia and pictures whereas the F3 wins at music and movie maker. See the comparisons here (copy past link in manually, link won't work in forum):
