here is actually a better build that you had on the site for 3350 (add another 100 or so for OS)
I honestly think you could drop 150 off with MOBO I chose and get the sabertooth. Also 16GB of ram is overkill 32 is off the charts. Get 8gbs stick however because your board support up to 64gb and you want to leave yourself room to expand.
All in all, your build can be done for under 3000 grand if you cut back in the right areas (Like I said 300 on a MOBO is more than enough, CPU fan, there are some great ones for around 40-50 bucks, ram you can get 16gb of top the line stuff for 90 bucks, case, I paid 80 for a full tower and i love mine, get the GPU you want, personally 2x 7950s is more bang for your buck, but 2x is a good bit more power if price is not a huge issue, do not skimp on PSU get the one I link too, it is awsome, overwise do not skimp on HDD or SDD they can easily bottleneck your system)
Also I used Tigerdirect for my build, I had a great experiance. But I only gave myself a 2000 budget including all accessories and monitor (my 2nd Mon and 2nd 6950 were on a seperate budget, bought them about 45 days after I got build going)
