SSD will be much faster; seat of pants you will see the speed, best speed increase for any PC with more than 4GB of RAM.
[I am Currently running X58 MB]
 
 ***You should be running Win 7 or better*** for TRIM to work on SSD; you failed to state the OS your using.
 
Your MB does not have SATA III ports, SSD will not achieve best speed; but, it will still be visibly faster than mechanical drive.  Current "new" SSDs are much more stable and are a great update to your system.
 
EVGA 170-BL-E762     http://www.evga.com/support/manuals/files/141-BL-E759.pdf
excerpt: page 8
Nine(9) onboard Serial ATA II + one(1) eSATA II
300MBps data transfer rate
Six Serial ATA II connectors from south bridge
with support for RAID 0, RAID 1, RAID10, and RAID 5

Setup your SSD:

1) So, backup important file to removable drive; Nice to Image (clone) drive also.
 
2) Get newest SSD controller software from Samsung. (or whatever brand you get)
 
3) BIOS, MB: best results NATIVE Intel controller SATA ports, set BIOS to ***AHCI - only*** (not IDE or RAID) Set Boot order to SSD as first drive when install of OS is done.
 
4) Time for a new install of Windows (preferred) Only install SSD; as MS Windows will place files in ALL HD that it can find during install; and if you later remove one of the HDs, Windows will not boot (Thanks Mr Gates) No sharp 90 degree bends in SATA cable, it can impact data.
 
5) Current main HD can be used for storage. Set Windows to save (My) documents, pictures, music, downloads to OLD mechanical HD.  Also non-priority programs should be installed on the mechanical drive.
 
6) Make image / clone of clean install after updates to New SSD; MS Windows, and again after all security software, lastly after final configuration of PC.  Much easier if you need to restore system later.
 
7) If you use the MS image software included with MS Windows; be aware that external HD on USB will error; just install a HD to MB SATA port to make image.  Remember to make a copy of your security key and logo on password reset, along with a restore disk.
 
8) Never- run a disk optimize function on SSD, just causes undo wear. 
 
9) Mount it anywhere, in case is FINE, there are no moving parts.  So, crashing heads not an issue.

When talking about PC, please use manufacture name and model number for clarity - Who made your E768?
 
Always put SSD on fastest Port your MB supports. Never bend shape 90 degree corners into SATA cable & use a quality cable for best results.


All SSD run their fastest on native Intel controllers -some MB do not have them and you can expect the SSD will not reach advertised max speed while benchmarking the drive.
 
SSD will make a real noticeable speed increase on any PC that is only using mechanical HD. 
 
Of course SATA-6 speeds are not available if SATA cable or port on MB do not support it.

Let the form members know if this helps you. 
Next time you may want to start a new thread of your own as the original post was solved and I just happened to take a second look today.

 The SATA-3 will be much faster in total data throughput. 
 
Thanks for the MB info for clarity; being an EVGA form one might have guessed it was made by EVGA; yet others have poste dother brands
 
My original comment was to address, that some people see their SSD does not perform as advertised when they benchmark the SSD. 
 
The fact that intel controlers are "the best" for SSD data throughput is just one of those things.  Not a reason to use the older SATA-2 Intel ports.
 
Quality cables are all good.
 
Enjoy your new drive.
