Not worth it. You can't just use AIO on a graphic card, you have to buy a bracket like the NZXT Kraken G10.

Total combined cost comes to around RM 330 - 350.

You're better off just selling your card for RM 400 (might be less than that) and buy yourself a GTX 960.

Costs you just a bit more but you get a much faster card (almost 2x the performance) that runs cooler (almost half the power draw).
