help me choose between 3 gaming rig thanks!

Go with option 1.

What's your budget? Option 2 appears to be a better overall choice quality wise. Don't get Corsair VS/ CX/ Builder/ CS, they use cheap capacitors.

get the second bundle, the asus board has nice features, the cpu is superior, the gpu is less by a little degree

Hi OP,

A) CPU
B) GPU
C) RAM

These 3 play a vital role in a gaming computer. Hence, my suggestion is -

Processor: i5 4690
Graphics: R9 280x
Ram DDR3: Corsair Vengeance 2X4
PSU: Seasonic 620w (Single GPU) and Seasonic 750 W (Crossfire)

If you are thinking to crossfire in the future, I want you to reconsider the above mentioned configuration. Why don't you go with R9 290X? You do not need to bother about crossfire when you have this (290X) card. It's a 'one man army' gaming monster which can render ultra graphics in almost all the high end or heavy graphic intense games. You can also put all your faith in Seasonic 620 W PSU which provides a big headroom for future upgrades because it has good build quality and a commendable ampere rating in +12V rail (Especially for a gaming computer). Provided you have made a decision on buying R9 280X crossfire, you can still go ahead but I would recommend Seasonic's 750 W PSU.

If you are going to overclock your processor to a small extent, you can still go with 4590 Non-K version. Though, Non-K versions are locked for overclocking, you can still play with multiplier in BIOS and enhance its speed, provided you have any Z chipset motherboard (You cannot overclock a processor without a Z Chipset Board). Click Here for the tutorial. This kind of overclocking can be useful for beginners.

And, do not install a single RAM chip. You will miss the opportunity of using the DUAL CHANNEL. Buy 2 (in nos.) 4GB RAM and insert them in same colored slots on the motherboard.

You can still move ahead with the AMD FX processors but their single core performance is far behind to the Intel's. Per core performance is must for a gaming cpu in which Intel has bagged its first place. By having this ability, you can really observe very low stuttering and choppy screen issues esp. while going through extreme graphics. So, performance-wise in gaming, Intel CPU is better and that's why I chose 4590. And don't worry about the bottleneck at all. The rig I've chosen for you has 0% bottleneck and hence you can see your graphics card and CPU working with high performance in all games.

Hope I've helped.

Edit: And here's my recommendation for motherboard -

MSI Z97 XPOWER AC Motherboard - Click Here

ASUS Z97 PRO - Click here
Asus is good to go because their motherboards are very special for Haswell CPUs.

If it meant you could get the 280x, I would go with a less expensive i5 4xxx and a cheaper board like the ASRock H81M-DGS R2.0. Another card to consider is the 280.

Try including a cooler in it, it'd be a basic necessity in OCing.

the ASUS board looks nicer and has higher quality
the FX 8320 is the highest CPU
there's no big difference between 270x and 280x, the 280x performs a better by 5% as I think
if you need the 280X card then get the third option with the Core I5 CPU but I'm not very sure about the board

The performance is sometimes negligible between 270x and 280x. I've got MSI R9 270X 2G Twin Frozr. I've superclocked the graphics clock to 1200 MHz and memory clock to 1500 MHz (Graphics Stock: 1080 MHz and Memory Stock: 1400 MHz). I ran stability test for more than 2 hours straight and found it working perfectly. It gives 7% performance increase.

Of those the 1st build is the best and will keep you happier longer than the other two (prob best in your mind also as you had it as #1
