Oh my, pai seh. =.=
With a fresher mind now. I realised I only pulled the GPU down to round up for the SSD and psu. If i recall, gtx760 was slightly better than R9 270x but at a slightly higher power consumption, i might further reduce if need be.
I will head down sls for a quick walkaround to recce for parts, casing and speakers.
3. questions in my mind now
1. about Superflower PSU the HX500, SF-500P14XE(HX). Is it really modular, and is the dimensions correct? Reason I trying to avoid is because the no. of pci-e 6 pin cables looks 1 short from the description and the dimensions seems different from the image [based on the image of the PSU it seems to be quite long]. Comparing from these 2 links

2. Possible to suggest a basic GPU for light use (compatible with matx or itx cases, regardless of 1200p or 1440p) around $250.
3. Would it be better if i change to amd build instead and balance it overall.
Edit - Question 1 answered by pct.
