I am building a new computer and am not sure which motherboard to get.
I can either get an H61 chipset 1155 MB which only has SATA 2 ports or a B75 Chipset MB with a SATA 3 port.
I also intend to get an OCZ agility 3 120GB SSD SATA 3.
The B75 is about £10-15 more expensive.
My question is will I be able to notice the difference (pure numbers/read/write speeds aside) in normal tasks e.g boot time, loading applications between a Sata 3 SSD on a SATA 2 MB and a Sata 3 SSD on a SATA 3 MB? Is it worth the extra £10-15?
On the SSD? Yeah, after looking on some reviews, you'll see some improvement over SATA2.
Though check the motherboard, make sure that the SATA 3 controller is one that's in the motherboard's chipset, not one of the 3rd party ones that run on the PCIe bus.
if the new PC is for gaming, i will say get the b75. Because the b75 has PCI Express 3.0 x16 for the new GPU like HD7XXX or GTX6XX which is nice feature but don't get much more FPS (frames per second). But who know in future.
For the SSD, if you can get OCZ Vertex 3 VTX3-25SAT3-120G or Crucial M4 128GB within $10-20, because OCZ agility 3 120GB is slow.
You can only notice the different between the SSD on SATAII and on SATAIII in benchmark but not in real world.
