upgrading from a8-5600k

[greatmanya]

Currently my specs:
Windows 8.1
A8-5600k 3.9 GHz paired with Thermaltake 2.0 water-cooling
FM2-A75MA-E35
8 GB 1866 Ripjaw
sapphire 6870 1 GB
600 Coolmaster PSU
Screen - 1920 X 1080

Now my question is, if I were to upgrade would it be wise to upgrade the cpu/mobo or just the graphics card or all three components?
I was trying to play Skyrim with 20 different mods on 1980 X 1020 when I noticed a lot of lag and wanted to upgrade for Skyrim and future games.
Basically this will strictly be a gaming pc with some multitasking here and there.
I don't have a high budget so if needed I can upgrade slowly- max $350
I was looking at i5-3470 and fx 8350 but cannot decide which one to get or even if they are worth getting. As for graphics, something like a 270X or 760 gtx.
But I am open to suggestions.
PS I am a Canadian so will be using NCIX.ca or newegg.ca or memory express - wherever I can find a better deal!
Thank you all

it will be better to upgrade all three....

get the i5 and a z77 mobo....since you already have water cooler....its better you go for the "k" processor

as for the gpu....go for the gtx760

you will need to sell off your existing components for this config though:

hey thanks for the reply! Do I really need a K processer since I will not be overclocking? That's why I was looking at 3470. Unless overclocking significantly improves, if that's the case would it be better to overclock the 5600k and get a new gpu instead?

over clocking does help improve performance a lot....as for your 5600K, even if you oc it till 6-7 ghz, it will not be able to perform like the i5..it will still be a bottleneck to the gtx760 or the gtx770

In order to save money, I suggest overclocking your current processor and getting a 7950. If you have room in your budget after that, go for an 8320 with an Asus M5A97 R2.

Is that coolermaster PSU an extreme series or a GS series? If it is an extreme power series, I would replace it before you do anything else to upgrade or overclock.

 

[greatmanya]

its the GS series

This is probably the fastest GPU you can get with your budget right now. Yes, your CPU will bottleneck it to a degree, but it is far faster than what you have now and will still serve you well when you upgrade your CPU and motherboard.
