Hello braxsusriely !
Your current thought for a swap of "Asus M5A97 Rev 2.0" is wrong choice for what you want. This board has 4+2 phase design only, and according to what I've and most Thuban users have clearly learnt that 4+2 phase is not enough for Phenom II X6 overclocking.
As I am seeing you like overclocking a lot too, and users like you must have a motherboard which has 8+2 phase design.
Here are some very important things I want you to understand which is essential for a good overclocker.
1.) What is a phase/VRM ?
A Phase or voltage regulator module in a motherboard is to feed required voltage and current to the CPU. It consists of a MOSFET, a Driver IC and a Choke. All these component makes a complete single VRM or Phase. Each Phase/VRM is capable to provide certain amount of Current. When we say 4+2 phase then it means 4 phases are for CPU core power and 2 phase is for Memory Controller.
Mostly each phase in a 4+2 configured motherboard can provide 35 Ampere of Current. This means 35 x 4 Phase = 140 Ampere max current.
This means All these 4 Phases are able to provide 140 Ampere current to CPU.
2.) Why do 4+2 phases is not good enough for high overclocking of Phenom II X6 ?To understand this you must understand these formula:
Power Consumption (Watts) = Voltage (v) x Current (A)
or Current (A) = Power Consumption / Voltage (v)
Now we know that default core voltage is 1.30 and TDP is 125Watts (TDP stands for "Thermal Design Power" tells us that CPU can transfer heat up to this rate at default voltage frequency settings in full load condition, in modern CPU we also estimate it as power consumption of CPU in a full load situation.)
How much current is required by Phenom II 1090T at default setting.
this will be 125 watts / 1.30 volts = 96 Amperes.
This means CPU will need 96 Amperes of current from your motherboard's phases which is 140 ampere max.
As you can see that 68% current is being eaten by CPU from what motherboard can deliver in a default settings.
Now what will happen when you overclock it ?
Motherboard's Phases might burn when they have to deliver more than 80% of current from the total. Because at this situation Phases becomes too hot to tolerate such heat. You either have to spend special cooling for VRM or have to deal with lower overclocking.
This is why we use 8 phase motherboard, so that the stress on the VRM/Phase becomes very low, because each phase now have to deliver much lower amount of current as the phases quantity is now increased to 8 from 4 for CPU core power. Now you have a lots of room to overclock your CPU
You also Looking to get better stability out of your 1090T. Don't you ?
All these boards have native AM3+ socket.
The cheapest 8 phase motherboard from ASUS is:
"Asus M5A88-V EVO" It is of of $90 only.
The second available cheapest 8 phase motherboard is from MSI is
"MSI 990FXA GD65". It is of $119.
Third available 8 phase board is from Gigabyte:
"Gigabyte GA990FXA UD3" This is of $139
^ Unfortunately all these motherboards don't have UEFI BIOS. And if you want to buy a board that must have UEFI featured BIOS, then choose the one from this link which have at least 6 phase (6 phase is enough for Phenom II X6, but they might be insufficient for latest 8 core FX CPUs ) and find in internet if it has UEFI or not. However UEFI is not a big deal, it just has some fast boot and secure boot feature for Windows 8 only.
