Which hardware for smooth 720p gameplay?

[admin89]

If you don't say anything about your budget , i will have to recommend i5 4670k + Asrock Z87 Extreme 4 or MSI Z87 G45 + CM Hyoer 212 Evo or better cooler and then overclock that i5

Your GPU is fine for 720p , maybe even 1080p in some games
Emulation = High-end (single threaded) CPU + Mid-range GPU
PC gaming = Mid-range CPU + High-end GPU
