adding new RAM modules

[HosTilezZz]

hi there people of earth

specs:-
motherboard: ASUS M4A88T-M/USB3
CPU: AMD PHENOM II X4 CORE 955 ( 3.2GHZ, 12MB total cache )
CPU cooler: cooler master V6GT
RAM: 2x2GB kingston valueRAM 1333MHZ CL9 1.5V
GPU: EVGA nVIDIA GTS 450 OC @ 882MHZ
power supply: XFX proseries 550w


I'm planning to get a "SAPPHIRE DUAL-X R9 270X" or "Gigabyte GeForce GTX 660 OC 2GB" and they both need at least 8GB to prevent any big bottle-necking (beside the one that my CPU is already going to cause), i can only find "Kingston HyperX Blu 4GB DDR3 1600MHz CL9 1.65v" for about 43$ and "Kingston HyperX Blu 8GB DDR3 1600MHz CL10 1.5V" for about 86$ but i can't find any 4GB 1.5v here sadly, so what is the best solution to get 8GB total RAM? should i just get the 1.65v and add it to my current 1.5v 2x2GB (i highly doubt this is safe)? ... and does these GPUs really need 8GB?

thanks in advance

For smooth gaming you will need 8GB of RAM, and its for OS not for GPU.

ummm... i live in Egypt mate so the total here would be about 75$ 😀 ( we <3 Egyptian taxes ), i would've simply purchased one online but it doesn't work that way here sadly :\

So you are stumped ! Ok go with this one "Kingston HyperX Blu 4GB DDR3 1600MHz CL9 1.65v", you may have to set the voltage in BIOS. But I am not sure if it will work on AMD setup, you can look here or online :
