For my pc build im going to be making this fall i've run into a bit of a snag in my planning. I've done a lot of searching and find that my plan to crossfire 2 R9 270x 4gb cards may not be exactly as good as I thought. I can afford either of these options but mainly what i've been seeing is that people recommend the single R9 290x card instead because of less power consumption and overheating, not having to worry about crossfire problems, and overall performance. I don't entirely know what to think so I was wondering what you smart people thought. Thanks!

Also just in case it either matters or you're wondering this is my planned build so far :

From personal experience, I always reccommend that you get a single most powerful card you can afford and then there is always the option to SLI/Crossfire later down the line. If you buy 2 270x's now, a year or two down the road the crossfire scaling won't match up very well and you would have wish you went with a 290x so you can crossfire those and get even more performance.

P.S. Good looking build by the way!

I'd get the R9 290 or 290X to avoid performance issues with the Xfire, also, some games may not work correctly with the 2x 270x

I would have gone with a single powerful card even though 270x cf would perform better,
But i dont wont to regret later.
And do get 2 sticks of 4 gb each to take advantage of dual memory.
Two card produce more noise and heat and less space for future upgrade.

Indeed. R9 290x but you may want to upgrade on the PSU power. I notice you have the H100i cooler. Perhaps bump the power to 750 or even 1000W if you decide that you are gonna go Crossfire with the R9 your gonna need it. Also the H100i has Corsair Link. If you do the RM HX or even AX series of Corsair PSU you will be able to link it to your cooler for a little extra monitoring and control if your into that.

Thanks for all the help guys, I will probably go with the R9 290x and upgrade the PSU. Without wanting to start a fanboy war, Im pretty set on going with the i7-4770K processor, but I was wondering if it will last me at least 4-6 years. Also I've done a ton of research but would the intel CPU be best for gaming and or overclocking or would an AMD CPU?

In terms of gaming performance there isn't any noticeable difference in fps between i7 vs i5, unless you are planning to do stuff like heavy video editing or cad or maya etc which get plenty of help from those extra threads. You will get barely 2-4 more fps in games if use i7. And for AMD, you need fx 8xxx or 9xxx series to match the performance of high end i5 or i7. Personally I wouldn't go with those cause they run very hot and have very high TDP especially those 9xxx series!!!!!! I recommend you to get the i5 4670 or 4570 which is also very good and save the money for upcoming Broadwell i7 processors which will be based on same lga1150 socket means you don't need to change your motherboard. This way you will have comparably newer processor and you will be good for 4 to 5 years ;)  And also buy a single r9 290x in future you will have room for more upgrade :)  :)  Hope I helped.

===========================
Note:- The i5 vs i7 difference I told dose not applicable on one game..... And that is "CRYSIS 3". The fps difference can be more than 10 fps. This is the only game that can bring an ultra high end pc to its knees. The simple rule of crysis 3 is the " more powerful the specs you can afford, the higher fps you will get" :D  :D

I'm also running Dual Sapphire R9270x 4gb. I would like to know what's the solution that you ended up with.
