I'm going to be ordering a gaming PC within the next few days, I'll mostly be doing things like photoshop and illustrator, but I also would like to get the best out of games like BF4 and Minecraft (with shaders) and with a relativly high 60+ FPS. I have the graphics card (EVGA ACX Superclocked NVIDIA GeForce GTX 970 4GB GDDR5) and the processor (Intel® Core™ i7-4790K 4.0 GHz 8MB) picked out. So 8Gb or 16Gb, ive been getting mixed opinions, and it is a $100 difference. Thankyou!
