Performance difference between 2nd gen and 4th gen Core i5

[Suvam Mandal]

Well basically few days ago my mobo got broken and my PC is totally dead right now.
My rig was-
Intel core i5 2310 2.9GHz
MSI ZH77A-G41
Sapphire AMD R9 270x Dual-X 2 GB OC
2 x 4 GB Corsair Vengeance 1600 MHz
Cooler Master Extreme 2 625w

As the mobo got broken, I have to buy another LGA 1155 Socket Mobo to support my CPU.
But no good LGA 1155 Socket Mobo available in market right now, only LGA 1150 are available.

So, my question is...
Is it really worth spending money on a new Motherboard and a 4th gen Processor or should I get a decent LGA 1155 mobo and use my old 2nd gen Processor. I recently got the GPU so I am in a tight budget right now, and does my old CPU bottlenecking my GPU? I was planning to buy i5 4670k and MSI Z87-G43 Gaming. But I want to be sure if upgrading really worth it or not (in gaming purpose).
Like how much FPS I will get after upgrading or stuffs like that.

Your old CPU seems to have good specs in today's standards. More often than not it is the GPU that causes frame rate drops in games, rarely the CPU. It seems to me the only main difference in the 4th gen is that it can be clocked up to 3.80Ghz as opposed to 3.30Ghz. Since you are on a tight budget, I would recommend getting an LGA1155 mobo so you won't have to buy a new CPU. That's just my opinion.

As turkey3_scratch stated, your current CPU is decent. The newer generation will be about 8% faster on a per clock basis, but if budget is a factor you should not be hampered in video games by your current CPU unless you are running a very high resolution.

You may want to look at the ASRock Z75 Pro3 motherboard at NewEgg. It is currently on sale for $67. Although it isn't quite as nice as your old motherboard, it should get the job done, as long as you do not run crossfire to another card.

Here is a link to the page on NewEgg:

But I heard that 2nd gen doesn't support PCI Gen 3 nor 1600 MHz RAM (it shows 1333 MHz whereas 2 1600 MHz 4 GB are there). Otherthen that, I can't find any cons except the 3.8 MHz Turbo speed in i5 3670k, so does it really matters? For current games or especially upcoming games like GTA V or Ryse?

PCI Express Generation 3, you mean. The 1333 MHz memory speed is the maximum officially supported for that processor, you should be able to manually set it to 1600 MHz if you know the timings of the memory as well as its speed.

All Intel I5 CPUs are generally preferred by gamers for their value and speed when playing games. They strike a good balance between performance and price. Your current CPU is old, but still acceptable. As I stated earlier, if you run games at a high resolution (above 1080p or with multiple monitors), then you may want to consider an upgrade. Otherwise your current processor should do fine.

PCIe 3.0 makes zero difference for graphics cards.

Well If I have to buy a CPU, which one will be better? AMD or Intel, because AMD is cheap in price and I heard it's value for money. Even the Motherboards are good with price values. I never used AMD CPU`s before but as my budget is tight and I am planning to upgrade it for future, which will be best...
Getting a decent LGA 1155 Mobo,
Getting an Intel Processor or,
Getting ab AMD Processor?

In my opinion I would say stick with your i5 until you honestly feel outdated!! I have the i5 2300 clocked at 3.0Ghz and it doesn't bother me even though my brother and my mate have 3rd gen i5's and 4th gen i7's and i5's...I haven't really seen any performance drops between mine and there CPU's most 2nd gen i5's are still high enough spec whether they are the 2500k or not!! But if you are going to upgrade then don't get an AMD I moved from AMD and never looked back at it...got better performance with my i5 and less heat problems which I'm not sure was the CPU or the case!!
