I'm going to build a new desktop mainly for gaming, and I've been thinking about which motherboard would serve me the best, under $160 Processor: Intel I5-4670 (Suggestions?) Case: Thermaltake Overseer RX I (Already ordered) Motherboard:
With your cpu, that does not permit overclocking, you can do very well with any inexpensive B85 based motherboard.
If you were to use a 4670K, then you would want a Z87 based motherboard that would allow overclocking.
That would give you perhaps 20% more cpu capability.
