Hi Guys, recently my 6 years old rig is... erm unstable. So may be it's time to change, may I ask for few questions? (My current rig is in sig, all are 6 years old except G-card)
It's a gaming rig:
1. Is it worth to invest DDR4 rig? (i7-5XXX and mobo)
2. If change, is GTX 970 more than enough or shall I wait for 980ti?
3. I'm simple gamer, so wont do much overclock, so no point buying the intel k series CPU?
4. I already have an 240GB SSD + an good old 1TB hd. Is it worth to replace the hd with fusion drive? Is SSD+fusion drive better than SSD+normal hd? (reason is I like to install game on the other hd, and will finish it before start next game)
I will plan my budget according to the feedback. (that means how long shall I starve to save up the $$)
Thanks in advance guys!

1. If you are power users and often do heavy rendering, you can consider 5820k as it is just a tad more pricy than 4790k, but it is hexacore vs quadcore of 4790k. But mind you, it not going to be helpful in gaming much (any time soon) and you probably need some overclocking to match the clockspeed of normal i5/i7. Other than that, an entry Haswell-E rig will cost just a little over high end 4790k built (I assume you getting value DDR4 RAM).
2. 970 is a mid high range card which is surprisingly powerful for its price and a beast for 1080p gaming. But as always, if you have the money to burn, the more powerful the better. But practical wise, I will say grab a 970 now and speculate how things develop in the next couple of months (AMD R9 300 series and Nvidia 980TI).
3. Yup, k series is for overclocking. And generally, overclocking don't provide much gaming performance improvement as long as the clock is over 3.5Ghz. Example, gaming wise, i5 4460 probably can handle what i5 4690k can handle.
4. Seperate drive is cheaper and easier to maintain. Hybrid drive is for laptop which having limited HDD bay. It is not a concern (generally) for desktop users.
Budget wise, I will say 4k for rig along provide you with a pretty solid specs for gaming.
