mr aniam ,
the whole point of going with amd is to decrease the cost of the components. i agree m5a97( * i made typo error there with "m5a95" in my previous post.) would be good match for 8320. but that mobo rev 2.0 will cost around somewhere 6.5-7k /-. then u again need a good air cooler too for 8320 to overclock which again will cost 2.5 - 3k for hyper 212,which will bring up the total cost around 20000/-. if going amd way, OP better buy fx 6300 with "that mobo"
at this price point it is better to buy intel 4670 non k which cost 13300(intel 4440 is 10900,intel 4570 is 12300) around at retail and b85 mobo @ 5000/- (or an h81 which is available at 3500 with lil bit of bargaining ). 4670 hands downs even at stock speed can beat oc 8320 easily.
and coming up to asus making sabertooth and giga pro not every motherboard is made with intention to overclock processors to 4.5ghz or more sabertooth and giga pro are made with quality components to handle that kind of overclocking as 8+2 phase give u alot of room for overclocking and that's where they make cheap mobo like 78lmt ( and i quote again rev 5 does support 8320
http://in.gigabyte.com/products/product-page.aspx?pid=4602#ov ** note is does have 4+1 phase with support to fx processors upto 125w ). offcourse since mobo is cheap it will offer very few options in terms of overclocking miss features like sli ,crossfire 32gb ram expansion, 1600mhz or higher ram option that high grade mobo like sabertooth offer (8+2 phase ) . but it will get the job done, which at the end of the day is playing a games which depends upon a decent cpu with a compatible motherboard and mostly on a good gpu.
"and r9 with that mobo (78lmt)" wow!!! u noob a graphic card whether it is r9 270 or hell even titan can run on any mobo and i mean every mobo as long as that mobo supports pci express expansion slot even 1.0 though there would some performance diff but yes u can use, however there is no difference in performance between 2.0 and 3.0.so any mobo with pci express 2.0 or greater can handle any gpu perfectly fine.
"and enough money to try" there are plenty of gamers that made a good gaming machine capable of playing games at good fps on that mobo and with that 8320 and fx 6300 and don't asking me for proof because who in the bluest of blue hell are u to hold me accountable !!! go search urself google would be a good place to start.
as far as "what am i or what i do" i am the one who knocks guys like u on floor. u biggest hole on earth neither does anyone give a **** about what u r or what u do.
and use that your knowledge on vrm,electricity controller ,capacitor to give urself some nice shocks on your brains and who knows maybe just maybe it could do wonders.
