So far I have everything but the PSU chosen. Is there a good standard PSU which will work for builds similar to this and is reliable and quiet? There are so many and there is hate and love on both sides of every one of them it seems.
Are there any bottlenecks in this build? Anything I could downgrade without sacrificing performance? Anything I need to upgrade or risk losing performance?
I'm considering getting a boot ssd later on, how many Watts would my PSU need if I did that?
Agreed. Wait until the i5 3570K releases, certainly worth the extra little as you can overclock, slight performance boost over the i5 2500K and lower tdp and higher efficiency.
As for $850 check out my $850 build here: http://www.squidoo.com/electronicandmore
Gives you SLI/CF @ 8x/8x on the motherboard, you get a PSU that would be plenty for Crossfire and SLI and the 7850 which is a great card. I'd just switch the i5 2500K with the i5 3570K when it releases.
Don't expect Intel to lower any prices on the chips. The 1st gen i7's and i5's are still the same price. Short and simple, even with newer releases, Intel doesn't drop down prices. The reason is probably that they don't want buyers to deviate from their newer line.
