Usage?  Gaming or gaming with workstation-related stuff?
Compact case?  Do you prefer microATX case, or mini-ITX cases?

SG09?

Prodigy M?
Though I'm not a fan of BitFenix designs...

Workstation as in 3D rendering? Why not nvidia? Sell 7870 and get a GTX 770/780/780 Ti

Do you plan to overclock your CPU?
Note that you do not need liquid cooling, and air coolers can be better than liquid coolers thermal and acoustic-wise...

Sidegrade bro...  Want better than go straight to R9 290/GTX780Ti...

Here's a youtube video hope it helped

encikapat, although it seems like a good idea to CrossFireX your GPU, but the stability of multi-GPU set ups are not very good, and you might have issues when playing the latest games, and will always need to latest drivers.

If you want to get more performance, consider selling your current GPU on LYN, and then with the added cash, buy a better discrete GPU, like a GTX750Ti for less than RM600, or a GTX760 for less than RM900.

You will have more fun playing games, instead of trying to fix things with a higher end single discrete GPU compared to CrossFireX.

It's a 4.3k budget right? Let me see what I can do. Want to try oc.

Proc - i5-4670k RM 759
Mobo - Asrock Z87M Pro 4 RM 349
GPU - Zotac GTX 770 RM 1200
PSU - FSP Raider 650w RM 270
HDD - 1TB WD Blue RM 189
RAM - 8GB RAM RM 239
Casing - Bitfenix Shadow RM 229
SSD - Intel 530 RM 349
Monitor - RM 716 Balance for monitor I don't know much bout Monitors

Without monitor will be RM 3,584. All the prices from Viewnet except PSU,GPU and Casing from GBros.

The 4670K is basically a non hyperthread version of the 4770K. So it works just as well for games or general usage and will last you a long time

But if you require more juice for multiple programs, then get the 4770 (non K version). Plug and play out of the box hyper threading. But without OCing. Which is you want to use for the long run is better anyhow since you're not overclocking for benchmarking purposes.

But if you still want to OC plus an i7 you'll have to sacrifice some of the monitor budget or get a cheaper GPU.

The i7-4770k is RM 330 more than the i5, imo i5 got is enough with it being OC'ed and all can last long enough.

Then be able to make some additions. My take on Zgames's recommendation.
Proc - Intel Core i7-4770K RM1050
Mobo - Asrock Z87M Pro 4 RM 349
GPU - Gainward GTX770 Phantom OC 2GB RM1,430
PSU - FSP Raider 650w RM 270
HDD - 1TB WD Blue RM 189
RAM - 8GB RAM RM 239
Casing - NZXT Source 210 RM159
SSD - Samsung 840 EVO 120GB RM320
Screen -  Asus VX239H RM699 (Great 1080p IPS screen.)
Total: RM4705.

You can still stick to the Zotac GTX770 if you wanna save some cash, or use the saved money to get a PH-TC14CS CPU Cooler from GBros at RM240. Comes it four different fantastic fan colors and it's a good complement to your OCed 4770K.
