It depends on different games. I don't time how long I take to boot games because they generally don't take too long. But since you can afford a R9 270x, then a SSD wouldn't stop u from getting 40+ FPS in most games.
The Asus B85M-E uses the exact same layout as the Asrock B85M Pro4, but like I said, the Asus board has less fan connectors.
The Asus B85M-E has
> 1 PCIe 3.0 16x slot for your graphics card , but the PCIe 1x slot just below it would be blocked by your GPU
> 1 PCI slot for older cards, or maybe a sound card
> 1 PCIe 2.0 16x slot ( running in 4x mode ) for a crossfire setup, or simply, another wireless adapter or something
I don't recommend crossfire though.
As for the fan connectors it has,
> 1 4-pin CPU fan connector
> 2 3-pin Case fan connectors
So you can only connect 2 case fans to your motherboard. But you can also connect more fans to the power supply using an adapter.
The Asus B85M-E is a great motherboard, but for $70, you could get a MSI Z87 motherboard
