Um,bavusani,three questions-
1)You already have that Corsair H60.So why add it to the total bill?If you want the 2013 edition,it is called the H60i,I think.Why not use your old H60?
2)You could try undervolting your CPU.I have and it runs cooler than what it used to be.I run my Rig for >12-14hrs daily.Have you tried that?
3)Why AMD-->Intel?I understand all your points about performance and power consumption,but if you can afford the whole expenditure of switching over for not a massive performance jump,then you should be able to foot a 3k electricity bill..Feel free to correct me if I am wrong.
The GPU of your current rig,isn't it bottlenecking your processor at 1080p?My 6850 used to and CPU usage was at 30-40% in windows task manager.Now,I have a R9 280X and cpu and gpu usage have balanced themselves somewhat.Again,correct me if I am wrong.
My suggestions for your rig :
AMD FX 8320 : 0
ASUS M5A99X(See below) : 11790
Sapphire R9 280X Dual-X : 23000
Corsair H60 (current) : 0
fans : 4300
-----------
total : 39090
I do not know anything about motherboards so I picked one that just looked good.Anyone is free to replace my choice of Motherboard.Though even with 55k,I have left room for a better choice of motherboard though I fail to see how with an air cooler,the overclocking room of his motherboard is increased.Afaik,Better motherboard=Higher overclocks=More heat produced=More effective cooling?
In case,you are having issues with your H60 not cooling enough,and want to go for a better air cooler ,the total (with Hyper 212 Evo) is 41890.But I do not know the overclocking headroom you would gain with air cooling.
