I have an older Rig that my wife now uses for whatever she can come up with, running a OC'd 3570k and my new rig using a OC'd 4670k. Ill say from personal experience that my Haswell runs hotter than her Ivy Bridge, its not much but its there, take that for what you will. Unless you plan on overclocking you might get more bang for your buck out of the non k version IMO. As for 780 vs 770, I have a MSI 770 Light Ed. OC and its amazing. I mean its the most expensive 770 and not that far away from a 780 but I plan on SLI down the road so meh. Its about cost, if your willing to spend the cash, the 4670k and the 780 are going to give you better results and better future proofing but again its all cost man.
edit: Ok so here you go, the cost comparison goes something like this. for the middle of the road 770 your looking at 430$ while the lowest prices on the 780s are around 630$ at 1080p I would honestly be more apt to pick up a higher end 760 for around 250+$ and that gives you a ton of savings with opening up the possibility for SLI with still not sinking overly large sums into one card. 760s also allow for 3 way SLI, so theres that. Ill say it again, cost rules the day boss, if you got the cash Id drop a mid range 780 into a 4670k setup and burn it up, but theres so much better cost per gain options that its all up to you.
the two answer are really good, and i like the theory of the fx proccesor about the 8-cores currently i have a amd phenom x 4 9650 at 2.3 and never let me down neither the graphic card ( ati shappire hd4870). the thing is that im not sure if im going to sli further down the road so meanwhile id like to have the best single gpu to play next gen games.
hi guys need help i don´t know wich is better for gaming on a 1080p monitor plus i want to use it for gaming with games like crysis 3 at ultra graphics
and last a gtx 770 or a gtx 780 for the same rig
as kirilmatt said, games and applications are using more cores now.
the FX is good for heavily threaded applications, like encoding and crysis 3.
a quad core is more than suitable for most games and applications, with most programs not even using all four. so, 4670k unless you can get a 3570k for considerably cheaper, if you plan on only gaming, with a little bit of modelling etc, and can spend the bit extra on them, and if you want to play only crysis 3 and BF4, and do 3d modelling and encoding, then go with the 8350, because of its ability to do better in heavily threaded programs.
the 780 will give better performance in crysis 3, so get one if you can. the 770 will perform ok in crysis 3, however it is nice to have a bit extra muscle if you need it. you still may need to turn down some settings, as even tri and quad titan setups struggle to run crysis 3 on ultra
