Hi guys so first of all I already have a GTX 660 in my system. I have an Intel Core 2 Duo E8500 and only 4gb of RAM (unknown speed). Is the processor and RAM bottlenecking the 660?

Anyway, I have about ~$70 to spend and I need a set of 2x 4gb sticks with at least 1600mhz DDR3, and it must be 1.5V and below because on my list I am getting a 4670k. Here is my list so far:
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor ($227.99 @ NCIX US)
Motherboard: ASRock Z87 Extreme3 ATX LGA1150 Motherboard ($109.99 @ Micro Center)
Total: $337.98

I do NOT plan to overclock yet with the GPU or CPU. Is the stock fan for the 4670 enough by the way with no OCing?

Anyway, I need a good set of RAM before I can purchase my new parts.

Any comments/suggestions on anything are welcome.
