so on offer up i seen a Asus z170 motherboard and it comes with intel pentium G400 cpu is that better than my gygabyte GA-EP45-UD3Pand my cpu is a untel xeon x5460There's no LGA775 CPU I would recommend for gaming nowadays as it's over 10 years old.
If that's all you can get though I've seen the Q9650 on ebay for like $20 but it's going to struggle on newer games.
Gaming wise, yes the G4400 is better due to the much better single core performance but I'd still wouldn't buy a dual core nowadays as newer games prefer more cores/threads.so on offer up i seen a Asus z170 motherboard and it comes with intel pentium G400 cpu is that better than my gygabyte GA-EP45-UD3Pand my cpu is a untel xeon x5460
