The only major difference I see is Hyper Threading. From the reviews I read I should be able to easily overclock the 4690k to match the speed of the 4790k.

Is there something I'm missing? My end goal here is to be able to play GTA V on max settings with a stable 60 FPS. I'm currently bottle-necked by my AMD 9370 FX.

I'll obviously have to buy another motherboard. I'll be doing some research there, but I should be able to use the rest of my other components.

Here's my current build:

• AMD FX9370 (8 Cores) Overclocked to 4.8 GHZ
• Corsair Hydro Series H100i
• ASRock 990FX Extreme9 AM3+
• Thermaltake 700W PSU TR-700
• ASUS Xonar DSX PCIe 7.1 GX2.5 Audio Engine 192K/24bit Playback Support Sound Cards
• G.SKILL Ares Series 16GB (2 x 8GB) 240-Pin SDRAM DDR3 1866 (PC3 14900) Desktop Memory F3-1866C10D-16GAB
• ADATA XPG SX900 512 GB SATA III 6 GB/sec SandForce 2.5 Inch SSD (ASX900S3-512GM-C)
• Sapphire Radeon R9 Fury X (4GB HBM)
• Cooler Master HAF X - Full Tower

The $100 price premium buys you a better binned chip that runs at 4.0/4.4; no overclocking is really required.
As you say, core speed is all important the hyperthreads will be largely unused.
Before, my advice was to buy the 4790K if the extra $100 was not that important to you.

Today,
With Skylake now available, there is absolutely no question in my mind that a new build should be Skylake.
1. Prices for cpu, z170 motherboard and ddr4 ram are almost precisely the same.
2. 6600K has an estimated 5-10% performance improvement per clock over haswell.
3. 14nm runs cooler, you get a decent overclock without the need for exotic cooling.
4. The Z170 chipset permits the use of much faster ssd devices on the horizon. Samsung 950 pro for...

I changed from a 4790K to a I5-6600K with a nice overclock, and for my type of games(civ-5) I can notice a benefit.

Yes, you will need DDR4 ram change also.

Hi Geofelt,

Thanks for the suggestion. You are not the first person to suggest the Skylake i7 to me. The whole point of me going AMD before was to have a little bit of a budget. As you can see with the recent purchase of my video card I kind of threw any budget out the window so I might as well go "all in" and buy the new fancy i7 CPU.

I'm currently looking at motherboards and I'm not certain which to choose: (Should I go with the cheapest one? they all seem so similar)

He is NOT recommending the i7, he is recommending the i5 6600k.

Actually, my suggestion is the 6600K, assuming you are willing to oc a bit. 20% more cpu is easy.

All three are similar, differing only in minor details.
Perhaps the most important is that the more expensive Maximus VIII Hero includes a better sound capability.

An alternative if budget is a big issue might be the Asus Z170M M-ATX.

I like smaller cases like the Silverstone TJ-08E

If it were me, I'd save the money over skylake. Just a couple builds for comparison.

Same motherboard to same motherboard from z97 to z170, cpu price difference plus having to buy ram runs $130 more. If considering an i7 6700k, may as well go with a 5820k and get 6 cores and twice the cache.
