Gigabyte GA-MA790FXT-UD5P Motherboard Compatibility: OCZ 120GB SATAIII Agility 3 SSD & SATA2

Hi!
I have a computer with a Gigabyte GA-MA790FXT-UD5P motherboard.
I would like to buy an OCZ 120GB SATAIII AGILITY 3 AGT3-25SAT3-12 SSD for it. We have concerns about whether it will be compatible with the board. The worst thing is that the board is sata2 and the drive is sata3. I will want to install the system and programs on the SSD, and keep the data on the current disk. Would I feel an increase in performance with this configuration, or is there any point in playing something like that. Normally, during normal work, I have Excel, Outlook, several Firefox windows, Photoshop, iTunes, Kaspersky, a video editing program turned on. I'm also going to add 16GB of ram to it and install windows 7 64 bit. The most important thing for me is whether it's worth buying an SSD drive, so that I don't throw money down the drain.

This drive has a transfer rate of well over 400MB/s with sequential read/write. SATA2 maxes out at 300MB/s.
Will you notice the difference? I doubt it. Because normal use is not sequential read/write and performance is much lower. With small files it drops to several dozen MB/s.
The jump compared to the standard HDD will still be overwhelming. You can possibly invest in a SATA3 controller, e.g.: http://www.ceneo.pl/16725093

A SATA3 drive will work fine on SATA2.
The mentioned SATA3 to PCI-E controllers are not worth much - usually their performance is not much higher than the performance of the SATA2 controller integrated with the chipset, so before you buy, I advise you to read up. The most common controllers have a Marvell or Asmedia chipset and it is on the basis of these controllers that I draw such conclusions.

The drive will run on SATA2.
But you will not use the maximum data transfer - max 300MB/s.
A regular disk has an average transfer rate of 100MB/s - so you will definitely notice the difference - the system itself will load much faster, but in other applications the difference will not be too spectacular...

In every application there will be a difference of +
It's not just about transfer speed, it's about access time.
And this parameter will be identical whether on SATA2 or SATA3.

Which is right, is right, especially since these controllers are PCI Express x1, which bus has a max bandwidth of 250MB / s :)

This is not true, the application loading speed will also be much higher. A friend also wrote that he deals with video processing. Here, too, you will notice an increase in performance.

Generally the answer is: it will be better in all criteria.
If it's not enough for you and you need to be sure of using the SSD at 100%, you will have to replace the motherboard.

I have Agility 3 connected to a sata 2 controller, transfers reach an average of 200MB/s, but this is not the most important thing ... the most important thing is almost zero access time to files and thanks to this I can, for example, open 20 windows one after the other without losing any speed opening them, there is no way to do something like that on the HDD, even if the transfer was 100MB, it would still be worth it...

Added after 8 [minutes]:

Alternatively, change the motherboard based on the P67 chipset, then you will be able to take full advantage of THIS drive. As above - the purchase of a SATA3 controller will not pay off, the results in HDTune are worse than after connecting the drive to the sata2 controller on the motherboard.

Thank you all for your help, I think the topic is exhausted.

I installed SSD OCZ 2.5" 120GB SATAIII AGILITY 3 AGT3-25SAT3-12 in the computer.
