Right, I am planning on getting the fx 8350 (I was going to get the i5 3570k but since I already have an AM3+ motherboard, I might as well get the 8350). I am getting it also because people are telling me my current phenom ii x4 965 BE will bottleneck the 7950 - the gpu i am planing to get. Right, so can someone work out how much more a year I will have to pay because people are telling me its like 60 dollars/pounds more to run! Is it that power hungry?
 
Well depends on where you live. I think it only costs around $20 a year here. Also all cpu's at that performance level are going to consume around the same power and its not really noticeable. If you are really concerned about power i wouldn't be playing games because that 7950 will consume much more power than your cpu
 
oh it will in cpu heavy games. Now if the only thing OP was playing is BF3 or something similar, than the bottleneck would be small.

 
The 965 BE is around the same in single-threaded performance when compared to the i3. Those two added cores for the 965 BE cause the i3 to be left behind in multi-tasking and/or multi-threaded scenarios.

Don't worry 'bout power costs; any difference will be made negligible by that monster of a card ya got there.
 


Arghh, people say it will and people say it wont. The games I play currently are
Minecraft
BF3
Garrys mod/TTT
Guild wars 2
Chivalry
Dayz

Will I get a bottleneck in these games, if not then thats the answer. Also, I am planning to get bf4 on either pc or the new consoles.
 
Your current CPU is using ~20W more than the 3570K would and 8350 is ~70W more than i5 when gaming. If you are going to OC, 3570K at 4.5 GHz would be eating about 130W less than 8350 at 5GHz.

Depending on what you are doing with your PC, you should go for 3570K with option to upgrade to i7 (if you are primarily gaming), or 8350 with option to upgrade to Steamroller ir you are using heavy multitasking apps (video editing, rendering and the like).
 

well OP wants to keep his mobo. Think the amd path is more cost effective for him
 



well its a pretty big gap when both cpus are at 100% load. but rarely does the cpu ever go there. When they are idle, power consumption for both cpus are about the same. As you increase load, power consumption scales in favor of intel.
 


This. :)
 


Calculate the cost yourself:

(Price of 1kWn in your region) x (load hours a day) x (FX/i5 delta in kW)
+
(Price of 1kWn in your region) x (idle hours a day) x (FX/i5 delta in kW)

You get the price difference for one day. x365 that and you get price difference in a year.

I.e. for me it woud be something like this (OC'ed i5 vs FX):
((0.2 x 3 x 0.13) + (0.2 x 7 x 0.02)) x 365 = 38.69 USD a year more with FX at 5GHz than i5 at 4.5GHz.
