Hey everyone, I'm just about to build my first pc as my current system bought 2 years ago is starting to seem a little creaky (it was never the best to begin with). I was thinking of going for an i5 4670k or i7 4770k on an Asus Z87-Pro MB with 8GB of 2400Mhz RAM and sticking in my current EVGA GTX670 Sig2 GPU. My current CPU is an AMD FX4100 on an MSI MB and was wondering if this will be a major improvement on my current setup. I could potentially wait but I'm starting to feel a touch impatient! The new build will be used mainly for gaming (DayZ, WOT, Elite Dangerous etc). I've no idea about the performance increases as I have no mates with powerful systems! lol... thanks in advance if you reply...
