Wondering why my decent gaming PC doesn't seem that impressive AMD vs INTEL

First off I'll go ahead and say in some points of my rig, I went way over the top, and in some areas I was a cheapo just because I did it in pieces.

I have a gaming rig that's been pretty good to me so far for the last few months. Before some changes I had a mobo/cpu combo that was an Asus Sabertooth 990fx r2.0 motherboard with an AMD 8350 black edition CPU. This setup was rocking the stock heat sink, and doing a fine job with no overclocking.


Now I have an Intel i7-4790k CPU with a Gigabyte z97x Gaming wifi-bk edition motherboard, and a corsair hydro series h100i liquid cooling system.

Other than those 3 differences everything else in this rig was the exact same as follows:

Case: Cooler Master HAF 932 Blue Edition
Power Supply: 750 watt bronze rated thermaltake "smart"
RAM: Only 1 cheapo ddr3 8gb Stick (1333 mhz) - <----- I think this is my problem?
Hard Drives : 1 SSD (250gb) running windows 7 Samsung
and 1 HDD (1tb) Seagate?
DVD: burner standard - irrelevant
GPU: 2x Nvidia GTX 660ti Graphics cards (SLI)
Sound: Sound Blaster card I got on Amazon for optical in/out


Here's what I've noticed with the difference between the AMD and the Intel chips. Nothing!
What I haven't figured out is why they both seem to perform the exact same. This comes from testing on old and new games alike. I know on benchmarks they wouldn't print out exactly the same but the intel doesn't seem any more crisp for gaming, video, or just processing performance.
And to be honest this PC performs nice, but I feel like it should be doing a lot better than it does. My theory is I screwed up on RAM and that it could make a better difference if I bought a decent set of 2 or 4 sticks. (Configuring them properly, of course.)

To give you a little background I have built only 5 PCs in my life and this one being by far the most expensive/advanced. It's very possible I could have missed something along the way. I really appreciate any input/info that you guys can throw my way.

Here's the sticks of RAM I was looking at getting :

Solution
I think you are limited by the graphics configuration, and not the cpu.
Some games do not scale with sli.

Your ram is not optimal, but it actually matters little.
There should be only a 1-3% difference between slow and fast ram on intel cpu's, their ram controller is very good.

If you want, you could add a second identical 8gb stick and you will run faster in dual channel mode.
A 2 stick kit is better than a 4 stick kit.

Solution
The ram will make a difference, but it's not going to make that much of difference, dual channel vs single channel. 8GB is also plenty.

I think the issue may be what you're doing with it. What exactly are you using it for? Have you overclocked your i7?

The two biggest benefits to Intel are the fact that they have significantly better single-core performance and they run a lot cooler, meaning more overclocking headroom.

Actually I'm mostly running stock configs. This Motherboard has an insane amount of control over voltage to every single core, and a whole lot of numbers and settings that I really don't know anything about. I went with the shrugging option and left it as is. I suppose I could look up an in depth tutorial on overclocking to give that a whack. I've monitored the processor under heavy loads and all 4 cores do not exceed 25 degrees (C) with my current clocking settings. I'm going to assume that is all stock.

Should I try to invest in a better GPU setup then? When I picked the GTX660ti I wasn't trying to get the best. But I wouldn't mind having something that makes my PC run better. What do you think I should shoot for?

Great thanks for the input everyone. I've decided to not sweat the RAM too badly and I'm going to focus on getting a new GPU. Looks like I'm going to get 1 gtx 780ti or one gtx 970 depending on my budget at the time. Thanks for everything again!
 
The i7-4790K is a great chip that should run at 4.0 with 4.4 turbo at stock.
No need to OC.
You might run occt to see how it does.
CPU-Z should show you the multiplier running around 43 under load with a vcore around 1.20.

It would be wise to confirm that graphics is your issue before spending a bunch.
Here is one way:
un your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.
