PCI Rom Priority

Hello All,

I recently upgraded my video card to a geforce gtx 960. After installation my system hung on the bios splash screen for a minute or two before booting. While not a huge deal I searched for a solution. I switched pci rom priority from EFI to Legacy. This did the trick and my computer boots fine. My question is...Does this change affect the performance of my new video card or system in general? If so, is updating the BIOS the next step (hopefully it's not necessary). System specs below.

Windows 7 64bit
Gigabyte G1.Sniper.M3 Bios Version F-7 (latest is F9 I believe)
Intel i5 3570k
16gigs ram
geforce gtx 960
500gb Samsung SSD Drive

Whether you are using a legacy or UEFI BIOS doesn't change anything in the performance. UEFI only adds support for secure-boot (which in my point of view is a worthless option), and allows you to boot m$ OS's from GPT disks (allowing access to more than 2TB on the OS HD, which also doesn't make too much sense, as the OS fits fine on a small disk, and you can always use an additional disk that is larger than 2TB and GPT for data, which you don't boot from). For Windows 8.x UEFI can also reduce the boot time.

what you probably should have set was your video priority to PCI-express first
