1333 DRAM? A Titan that is almost twice the cost of a 780 for a few FPS? Overpriced mobo and not utilizing it?
Aznricepuffs has a couple good builds (3 monitors on second build though instead of 4), also if looking ahead would suggest 16GB in 2x8GB and witht he scaling abilities of Haswell, go 1866 at a minimum
In that case would look at Aznricepuffs first build, go to 16GB DRAM (suggest Tridents 2x8GB 2400/10) and add a second 780 in SLI, though I'd suggest the Asus CU model for the better cooling, and change the PSU in his build to a SeaSonic
I should have pointed out that I already have the monitors so we can put that funding into the computer if it will improve performance.
Once you get past a certain price point (really around the $2000 - $2500 range) the differences in performance are marginal at best. For instance there's only a 10 FPS difference between a dual GTX 770 and 780 setup, and a 10 FPS difference between a dual GTX 780 and Titan setup. The i7 and extra RAM don't really do anything to increase gaming performance.
Dropped the monitors from the budget. Added another 780 and upgraded the PSU from my original build. You can go for 16 GB RAM if you want, but it really won't help that much for gaming. It might help if your website development is graphics-heavy and you end up doing some intensive graphics editing work.
