text: My current build I run an AMD based System... to be more specific an AMD fx6300. Inevitably I will upgrade to and Intel based system when I have the money to spend... My question is in terms of gaming, what sort of advantages would an Intel CPU provide compared to my AMD CPU. Also what is the difference between an I3, I5, and I7? Obviously and I7 is the higher end of the Intel CPUs, but would an I7 make a significant difference in performance compared to an I3 or I5? Finally, if i were to upgrade to Intel today, which Intel processor would be the best to buy for price and performance.
  I play games, like Battlefield, Dayz, Far cry 4 at 1080p
  Eh Intel has never made anything that was price to performance oriented (unless you consider the Pentium Anniversary Edition which, DON'T) the difference between the i3's and the i5's is the core count. that's about it. i3's are Dual-Core, i5's are Quad-Core. the Difference between the i5's and i7's is Hyperthreading, the i5 is 4 Logical Cores each with 1 thread, the i7 is Quad-Core with Hyperthreading. in other words each core has two threads instead of one. that's it. the i7 makes sense if you are doing more than gaming maybe a bit a video editing. but if you all you are primarily doing is gaming if an i5 is really recommended. you'll be perfectly fine. and i7 really doesn't make sense if you are gaming you aren't really going to see a benefit, maybe a frame or two, but it's not worth spending an extra hundred on an i7 if all you are doing is gaming.
  now what i recommend for a gaming PC is a 4690k. that is the most reasonable. that is the best you are going to get for your money (if that even makes sense)
  Basically summed it up nicely.
  The Pentium is basically just for people who wanna have fun OCing it. Not really a powerhouse of a CPU. It is a tad slower than an Athlon 760k.
  i3s are dual-cores with HyperThreading, i5s are quad cores, and i7s are quad cores with HT. The exceptions to this are the Socket 2011-3 i7s which are 6 and 8 cores with HT. On the mobile side these things are different though but that is for desktop parts which is what you're interested in.
  HT does not make your quad core into an 8 core despite what some of the fanboys say. It is only useful in productivity applications like video editing and will give you no benefit in game.
  The benefits with going Intel is better single core performance which some older games and ones that are poorly optimized (like DayZ) prefer, you get a newer platform as well which has some nice features but of which none are really super necessary (PCIE 3.0, M.2), and lower power consumption.
  I'd go with the 4690K if you want to game and the Xeon 1231V3 if you don't want to OC and want to game and do productivity. (The Xeon is essentially an i7-4770, so a quad core with HT, without the iGPU and is around $30 more than the i5 or $100 less than the i7. It just can't OC. You can also use ECC RAM with it if you want which is good for workstations and servers).
  i3s, Pentiums, and certain Celerons also support ECC memory. OP won't need the feature, but they're decently cheap options if somebody wants to build a cheap NAS or small server.
  Totaly agree with Kat´s story ☺
  the i5-4690K is basicly the best cpu for gaming at the moment. The i7 is not worth it for gaming, simply because games dont use more then 2 or 4 main threads. The 4690K also has the best ipc on the market.
  There are only a few games that are capable to utilize all availeble threads, but this still does not results in better performance for the i7 over the i5, only less load on the cores. But that doesnt matter.
  Intel vs AMD is basicly a never ending debate. But it just highly depends on the games you play mainaly, The i5 is simply the better allrounder for gaming, especialy on 1080p with a higherend GPU. This is because intel cpu´s have a much better ipc, and single threaded performance, which still makes sense in cpu bound or cpu + gpu bound gaming scenario´s like MMO´s and multiplayer especialy on minimum frame rates.
