Kneel down and ask the Great God to install E5 mainframe for PS LR in the later stage of photography.

E5 is not recommended for photo retouching. The price of x79 motherboard e5 6 core CPU is about 700-800. Your memory is only useful for 4gDDR3, and the other two are DDR2, so it can't be used. No matter how bad the graphics card is, it should be bright. Hd7750 should be above 100, and solid 120g should be above 100. Basically, it's in the early days of 1000. If the memory is increased by 4 G, 1000 can't be eaten.

Because your requirements are not very high, I suggest you use x3440 with p55 motherboard. A better set is more than 300, plus the graphics card hd7750 100, the solid 120g is about ***600. You can add 4g memory if necessary. Enough for you. In addition, you have to see if there is something wrong with your old equipment, that is, the graphics card! Make sure.
