I second the 990FX chipset over the 970. Aside from more and faster SATA ports and the ability to crossfire/sli much better, they usually have the ability to support higher power demands from you CPU so you can get better overclocking results. Generally just an all around better chipset and not much more than competent 970 boards. As for brands, I'm not really sure if there are any to stay away from, but I have heard that Gigabyte, ASrock, and Asus (My personal favorite) are the best. Also, I highly recommend this site for choosing your parts, it will tell you where the prices are lowest from the best online retailers and will also make note of any promos and price cuts.
As far as RAM goes, I've always stuck to Corsair and GSkill, I have AMD RAM in my most recent build and it works flawlessly, but costs a bit more. I'd recommend GSkill for the best price/performance RAM.
Your post came a little late and i have already bought parts is ASUS M5A97 R2.0 970 chip a big loss over 990fx, or none at all ?
Ah oh well. Nah not really a loss, they will perform very similarly just that the 970 won't run dual PCI 2.0 @ x16 bandwidth, so it's not nearly as good for crossfire or sli. other than that, the 970 appears to have a slightly slower hyper transport speed, 2 less power phases, and a few less SATA and USB ports, but the SATA ports are still isted at 6 GB per second just like the 990 FX pro. If you don't plan on running dual GPU's and high overclocking the board you bought will run perfectly fine. Personally, I'd stick with it rather than return it for a 990FX one. They will both perform similarly in a rig with one GPU and will both overclock your CPU decently.
I dont plan to overclock at all only turbo mode and no crossfire aswell, but what does exactly this means, try to explain it like you would for an complete retard, so its easier for me to understand" slightly slower hyper transport speed, 2 less power phases"
Ok then you will be fine with that board. The extra power phases allow for more stable and more overall power to be fed to the CPU. In other words, a board with more phases can support more power going to the CPU, which is only really relevant when overclocking or running a high power CPU, such as the FX 9590, which uses 220W which is essentially a factory overclocked 8350, which uses only 125W. A CPU like the 9590, or a heavily overclocked 83XX will most likely be more stable on a board that uses more phases as they will use more power when the frequencies climb, and also since there are more phases the wear and tear factor from overclocking is less of a worry. I believe the highest end Asus AM3+ boards like the Sabre Tooth and Crosshair V use an 8+2 design, which is why the record holders use them and other similar 990 boards for super extreme overclocking.
Hyper Transport is the speed that the system bus in AMD systems run. It handles the RAM to CPU communications and basically all communications with hard drives. Kind of like a link from the CPU to everything else attached to the board. I think it handles communications between the CPU and GPU as well. It is basically AMD's version of Intel's front side bus, which does basically the same thing. Hyper Transport is capable of higher RAM clocks than Intel's system, which is why AMD CPU's always support higher RAM speeds. In fact, all current FX CPU's can run 1866 RAM without overclocking where Intel tops out at 1600 (I think, it's possible their new CPU's might support faster RAM), and anything faster requires a special memory profile loaded into the RAM sticks themselves or manual overclocking in the BIOS. It's also the main reason that AMD rarely needs to make new sockets for their new CPU's and retain backward compatibility, such as a Phenom II CPU made in 2009 running on a board made in 2012 that can also run an FX 8350. The HT speed would be lower for the old CPU, but it would still work fine. All modern AMD boards run HT 3.0, the newest version of Hyper Transport if I remember correctly, but some lower end boards are slightly slower in their rated speed. I'm not really sure exactly why that is, but it is not much slower on 970 boards and most likely the end user will not notice the difference unless they are benchmarking their hard drives or something like that. The RAM and CPU will keep the clocks they were designed for no matter the final speed of the HT link.
A little long winded, and I may have missed a few things but that's basically how it works lol.
