a 4ghz phenom x4 shouldnt have an issue with the 7870 with an OC, and changing the priority in task manager will just make the program that has the high priority obviously have priority over other background programs and will be processed first but i dont see changing priority will help much unless ur running alot of programs behind what ur mainly doing
In Crysis 3 CPU Cores in some places go up to 100% (Overclocked to 4.2GHz), and this cpu bottleneck one HD7870 in this game. I was thinking to buy FX8120? Will it be much better in Crysis 3 and other CPU heavy games where Phenom X4 955 can't push HD7870?
Get a 63xx or 83xx the 81xx & 61xx are little better and sometimes worse than the Phenom. Alternatively you casn wait to see what Steamroller offers around the end os the year (thats what I am doing nothing so far has tempted me away from my Phenom x4).
I have a FX-6350 OC to 4.5 GHz on air and I'm happy about my switch from 965. I'm in the FF14 beta and I'm a hair shy from running the game on max @ 1080. Also note that this game isn't the optimized final product. Cheers. Edit: I forgot to add that it's much easier to cool 6 cores opposed to 8 on air.
Well, if you went to a 6 or 8 core FX, the good news is, if you get a good 990FX board...(like a sabertooth for example)...you would be able to just update BIOS and drop in a new steamroller FX when they hit. The socket will be the same! Plus some of the newest 990FX boards have PCIe 3.0 support as well as other nice features like USB 3.0!
If you wanted to upgrade, I would look at something like a 6300/6350 at minimum...if you want to "go big or go home" then I would look at the 8350. The 8320 is a decent option as well, but the 8350 is higher binned and typically has a little more headroom for OC.
