Asus p8z77 V LX is a good board for overclocking and I have given references about V LX many times in the forum.
V LX lacks VRM heatsinks and SLI support(not important in mos of the cases),but still is quite good.
VRM without heatsink= VRM overheating = not safe for 24X7 overclocking.
Intel i5 3570k -14k
ASRock Z77 Extreme6 -12.5k or Asrock Z77 extreme4 -10.5k
G.Skill RipjawsX(1600MHz)(F3-12800CL9S) 4GB*2 - 3k
Corsair cx500v2 -3.3k
WD caviar blue 1TB -4.8k
NZXT source 210 elite -2.6k or CM elite 311 plus -2.7k
Asus DRW-24B5ST - 1k
Don't buy gtx650.HD7770 performs better than gtx650 and costs lesser.
Alternatively,if you can sacrifice overclocking then you can get i5 3550+h77mobo and use the saved money for a better card like hd7850 or gtx660.
For mild/moderate clocks temperature won't be that high.
This board costs only around 10k,so 24*7 sustained overclocks with high clocks would be too much to ask from this board.
