Ugh it has to be my MB. I just installed another of the same card and its still the same handicapped frame rate
That's annoying. The only way to test for sure is to put one of the cards (or both in turn) into another computer with a CPU fast enough to avoid bottlenecks. If the GPU performance is better there, then it could be the motherboard.
Have you observed the CPU and RAM usage during these tests? If the CPU is maxed on
any single thread, the bottleneck would be the CPU. So don't just look at the over all usage. For instance, if you had a quad-core i5 CPU (just to keep the example's math simple), then you could have a CPU bottleneck at only 25% overall CPU utilization. That's because one of the four cores could be maxed out, and the other three could be doing nothing - a net usage of 25%. Certain games and programs are poorly coded and overload too few cores without using others.
To check your per-thread CPU usage in Windows 10 or 8 (Win 7 display all threads by default), open Task Manager (ctrl+shift+esc), go to the "Performance" tab, select "CPU" from the left side, right-click on the ticking graph on the right, hover your mouse over "Change Graph To," and then be sure "Logical processors" is selected. Instead of showing overall usages for all cores and threads combined, there will be a graph for each thread. On your i7-5820, that should display twelve (12) threads (viz. you have six cores that can handle two threads each). See what's going on in that view while you run the same benchmarks or games. That same tab will also show your RAM usage.
It's worth checking these things. Getting a new motherboard is a pain. You have to take everything apart, put it back together, and then you have to resinstall everything on the computer because Windows thinks it's an illegally hacked copy when you swap motherboards on the same installation. So that means backing up everything first. If Windows was installed on your computer when you bought it, then you will have to also buy a new copy of Windows because you have an HP OEM copy of Windows. That means there is no product key for you to enter. The "product key" is built into your motherboard on computers from HP, so swapping out the motherboard essentially throws away your copy of Windows with it. HP is not permitted to give you another copy because it's technically illegal. The point it, if you buy a new motherboard, also buy a RETAIL (i.e. not OEM) copy of Windows to go along with it. Back everything up you care about, fully delete your system drive, and then rebuild the computer's software from scratch.
If you have the time and money, then it's a great learning experience and good practice if you'd done it before. Just a very involved process, so expect to dedicate most of your weekend. I'd guess $300 and 12 hours would be your money and time investment in order to get everything back in full working condition. That includes all of your programs, data, and customization - if you know what to do. If not, it'll take longer, but you can still do it. it's just that researching stuff along the way takes time, so start early in the morning if you decide to go that route. Good luck!
