New 750w (Semi)Modular PSU

I'm needing a new PSU and was wondering between 2 750w.
Ones semi modular:

And Ones just modular:

I'm upgrading from a CX 430w and am planning on sliing 2 970s later on, so which one would better suit me? Thanks!
 
Solution
semi modular usually have the motherboard big power cable hardwired and the cpu power cable so 99% of cases you need those cables anyway. so i'm tempted to say no
