Bios Mods -The Best BIOS Update and Modification Source

I have the P6T Deluxe v2 board and I have a very old Intel RAID ROM (ver 8.0.0.1038). I am new to modding and I am trying to find out if I should update the Intel ROM

Windows 7 Pro 64-bit. Currently I am running;
BIOS version 1202
Intel ROM - 8.0.0.1038 (set to RAID)
Intel RST driver - 12.6.3.1000 (using RAID driver)
Using Intel SATA ports for single drive SSD and single drive HDD (SSD has the O/S)

Did tests using AS SSD, CrystalDisk and Anvil, per the numbers this gave the best numbers in testing for me using the past 8 Intel RST drivers in both AHCI and RAID mode. See attahced

So looking for some advice and numbers to see if I should update the Intel ROM. Or maybe if someone can explain why I should update the Intel ROM since as I mentioned, I am new to this.

Thanks

Another question, can you update the OROM and then just restart your computer or do you have to do a install? Or will an image work?
