how is this build? The 2343BWX monitor that was suggested I cannot find at NCIX, weird

. Would this build be the best(longest lasting) I can do with 1400 after tax (basically 1300 before tax is calculated on) ?
1055t phenom 2 x6
crosshair 4 formula
2x2gb g.skill trident ddr3-1600
Western Digital Caviar Black 640gb
BenQ 2412HD
Antec Basiq 550Watt PSU
CM690 2 Advanced
Corsair H50 CPU water Cooler
Samsung SH-223L SATA optical drive
5850 whichever is cheaper
thanks guys for your input! really appreciate it
