Howdy folks, I'm building a new system soon, and these are the parts I have selected:
CPU: Intel Core i5 3570K 3.40GHz LGA1155
Cooler: Coolermaster Hyper 212 EVO CPU Cooler
Motherboard: Asrock Z77 Extreme4 Motherboard
HDD: WD Caviar Blue 500GB WD5000AAKX
PSU: 750W "Silverstone" 80PLUS Gold ST75F-G
RAM: Corsair 16G (2x8G) 1600MHz CL9 Vengeance CMZ16GX
SSD: Samsung 830 Series 64GB SSD
Case: Corsair Vengeance C70 Mid Tower Gaming Case Military Green
Graphics Card: Gigabyte Radeon 3G HD7970 OC
I'm most concerned about the graphics card. If I use this card with my current motherboard, will it ruin my future system? Lurking around the internet, I've heard the term 'bottlenecking', and I'm afraid something similar may happen to this system I am about to build.
2x4GB. That way you can take advantage of the dual channel configuration on the Z77 platform.
While this does limit your upgrade path to 16GB, that's is the most you will ever need. Any usage that would need more than that is more suited for the X79 platform.
