Board and CPU upgrade Questions

[newguy212]

My current system is,
CPU:Intel Dual-Core G2010 2.8,
Motherboard:ECS Board (I forget the name)
GPU:GTX 660
PSU:FSP 500 watt 80+ Bronze
CPU Cooler:CM Hyper TX3 EVO
1TB WD Caviar Blue
8gb Dual CH Ram
And now I'm planning to change my CPU and Motherboard to MSi 970 Gaming for the board,and AMD FX-8320 for the CPU,why?,because first,the reason why I choose the FX is because it has 8 core,and I wanted a future proof CPU,and I don't really need a 100fps or more,any game that is above 30fps or on 30fps on maxed settings is fine by me,correct me if I'm wrong but games are starting to use 3 cores right?,and I won't be gaming on 1920 X 1080 anytime soon,and I choose the MSi 970 because I might go SLI with my GTX 660,now my question is,one,without SLI,do I need to upgrade my PSU to a higher wattage? if yes,then how much more? ,two,will this build work?,and lastly if in the future I decided to go SLI how much power do I need,650,or 700 watt?,that's it,your help will be very much appreciated

8320 will be fine for gaming, cheap option. However, it will most likely DIE before games utilize 8 cores. You can't really "future proof" past like... 2 years. If even that.

Your PSU will support most 970s (with 500w power requirement), you will have problems with like a 970 G1 from gigabyte for example (it has a higher power requirement). Your PSU will NOT support GTX 660 SLI.
700+ recommended for 660 SLI if you plan on overclocking anything...

But, the 970 is overkill for 1920 x 1080 anyway.... so there is absolutely no reason to buy a 970 if you don't plan on switching to 1920 x 1080.

Alright,so it's all O.K then,just some overkill,and yes I might switch to 1920 x 1080,but not like next month,more like next year,and oh one more question,should I go with Win 7 or go with Win 8.1?.

Which ever operating system you prefer.
