Looking at the UD5, but is no sata3/usb3 important?

OpenToSuggestions · 14 Mar 2010 at 22:20

Hi all.
I built a friend an i5 750 rig yesterday with the intent of 4ghz and now I want one!
The ocuk price for the Gigabyte UD5 is good, but I am concerned that in future months I will wish it had usb3 or sata3.

The refresh of these boards are much more expensive (not even in stock at ocuk at the moment), even though aside from sata and usb they are the same.

My SSD only really goes to sata1 (150mb per sec) speeds. I know it is the OCZ Vertex but realistic speeds are still within the sata1 region.

Is Sata 3 merely a marketing ploy right now??
If I need USB3 I could just get a £10 pci card in a years time.

Thanks

I think you've hit the nail on the head. The only thing really worth it (as far as I can tell) is USB3.0, and of course you an just get a PCI card for that when it is actually in wide use and you need it. Even then, there are still going to be a lot of USB2.0 devices being released, because not many people will have USB3.0.

I think I'd rather have SATA3 than USB3.0:-

that said I don't think I'd buy a board now that didn't have either USB3.0 or SATA3.

wait until you have a device that requires the interface and then get an add-on card. That will be about a year

I would never spend that kind of money on a hard drive!

What I was thinking is, even though the theoretical max speed speed is over 300mb/sec it will likely never ever be like that and normal read and write surely won't be. My OCZ vertex is no-where near the claimed speeds.

Also I read that the SATA3/USB3 boards limit the pci lane to 8x when using sata3 or usb3?! Anyone heard about this??

It's news to me. I thought that a new SATA/USB controller is what is needed, and they are not connected via the PCIE lanes?

That's only if you're using crossfire and only on the P55 motherboards.

Can you expand on this? My understanding is that the pcie lane is slowed down to 8x when using sata or usb 3 (assuming that is what turbo mode means) even when using one graphics card.

Turbo mode is where the CPU will shut down one or more cores, and overclocking the remaining cores that are needed - this can be useful in single threaded applications, where the other cores are useless.

I don't think you need to worry a great deal either way.
