A rig that doesn't compromise the performance of the gpu in any way. No bottlenecks. Also, I don't want it to be way above of what's trully needed. Like 32 gb of ram, that is bullshit. The most intensive tasks I'll do its gaming and I believe no game is optimized for more than 8GB. Don't give a fuck about RAM disk.

Also, no dedicated sound card is needed, since I'm partially deaf, I just use headphones all the time anyway.

And no watercooling, no overclock, no disc drive. 

Anyone has some recomendations ? :)

I'd go with an Intel CPU, probably the i5-4670K (or the non K version if you won't overclock) paired with a Z87 motherboard (no need for a high end one), 16GB of 1600MHz RAM, a 650W power supply of a reliable brand (modular would be better) or a bit more if you plan to go Crossfire in the future, and a case with lots of ventilation and fans, something like an Antec 902.

Also, a small SSD for OS and other software and a 1 or 2 TB fast, traditional HDD (like a WD caviar black) to store lots of games. Or if you want/can afford, a single 500 GB SSD for OS and games but then you'll have to delete games more often as you'll fill it up rather fast.

You will always have bottlenecks, it's impossible not to, demands on a system changes depending on the game or even what's on screen as to whether the GPU or CPU is going to be under the most load.

I do agree with JEMC on the CPU and Ram as well as the motherboard, especially the Ram, don't bother with 8Gb, 16Gb is the sweet spot and will give you plenty of room to move for many years to come.
I do disagree with the case though, avoid Antecs like the plague, they are dust magnets, Corsair Carbide cases are solid pieces of kit. - Be aware though Corsair Cases aren't exactly known for the best airflow. (Which is fine if you go closed water cooling.)

Get yourself a decent case and Power Supply as they both will/can outlive the PC.
Something along the lines of the Corsair HX/AX or Seasonic X-650/Seasonic XP-660 if you intend to stick to single GPU's, go for the 800-850w models if you even remotely intend to go Dual-GPU in the future.

I suggest waiting a year if you can... There are a few hits and rumors that the next Intel CPU refresh will support DDR4 and Ram gets refreshed every 5-10 years so... I think its worth the wait

The next refresh will bring about a few % points of improvement in the consumer space, that's status quo.

DDR system memory speeds generally do nothing for video gaming unless you are using on-board graphics, which the Op won't be.
Besides from what I can gather only Haswell-E on the Socket 2011-3 platform (I.E. Successor to my system) will be supporting DDR4 to go along with the 20% IPC improvements and 33% increase in core count.

When Intel moves the mainstream to a new socket then you might get DDR4, but that ain't happening for at-least a year as the current socket will get one more CPU release. - By that time scales of economies would have kicked in making DDR4 more affordable.

Basically, don't wait, do it now and enjoy it, if you keep waiting for the next thing in the PC world, you will wait forever.

I mentioned the 902 because 1) It's cheap, and 2) with a 290X you need a case with very good airflow, and that case is cheap and has lots of ventilation.

What's your opinion on the CM 690? Or NZXT Phantom cases?

get a high end i7, 39xx or 49xx and youre good to go for years.

I like the Phantom Cases, purely for looks. - Lots of enthusiasts enjoy modding the hell out of them too!
The CM 690 is a good case.

Also guys, will a 290X stutter at 2560x1440 resolution on highest settings ? I can wait till june, but I wanted it this christmas :)

I'm not much keen on 4k right now, but 1080 on a big screen right in my face just doesn't cut it. There are many games that support 1440p already, I think 2.5K is the sweet spot right now.

I'd go with i7-4770K personally since games will be more tuned for 8 threads due to new consoles for optimal performance. Usually a bottleneck these days is the use of HDD for games instead of SSDs in Raid-0 which I'd highly recommend, you'd think loading doesn't mean shit but it always does, just be sure to turn off your page file when using SSDs. 32GB of RAM is only good if you run VMs, otherwise 16 is enough for now. You also need to do some research on motherboards to see which one fits your style. Case doesn't matter as much if you pop fans in and take air out at the top, and use http://www.amazon.com/Metro-Vacuum-ED500-500-Watt-Electric/dp/B001J4ZOAW/ref=sr_1_2?ie=UTF8&qid=1383413688&sr=8-2&keywords=air+blower on it outside of your residence every 6 months or so (and hell of a lot cheaper than canned air in the long run.)
