Can I upgrade my computer configuration?

You mean, you continue to use the original i5 3470 and 8G memory, and replace all other accessories with these accessories you wrote?

There is a problem with your configuration.

First of all, your original i5 3470 is 1155 pins, which is not compatible with the Z97 motherboard, and your CPU can't be plugged in, and you can't turn it on.

Secondly, even if you change to i5 fourth-generation processor, do not have a CPU with K, do not match Z97, waste the biggest function of Z97 overclocking, it is a waste of money, it is recommended that you change the motherboard to B75 series, which is compatible and does not waste money, if your original motherboard is B75 or Z77, it is recommended to continue to use it, do not change the motherboard.

In addition, GIGABYTE's 970 G1 performance is really powerful, only slightly weaker than Colorful Nine Duan and Zotac Extreme, but the power consumption is very large, and it is also more CPU-eating, i5 3470 is difficult to fully exert its performance, the minimum recommendation is 4690K or E3 level CPU to perfectly exert its power, especially the 970's physique is very ......

If you change your CPU to the i5 fourth-generation CPU without K, or E3, with GIGABYTE 970G1, the bronze power supply rated at 450W+ is sufficient, and it is recommended that FSP Black Knight RA450 or Antek Eno Eco 450M, both power supplies are 12V single output, with a power of more than 400W, which can completely drag you to this configuration. There is no need for a 650W power supply. Because the power consumption of the 970 public version is only 145W, the measured power consumption of the GIGABYTE G1 is only a little over 170W......

If you change to an overclocked U like 4790K or 4690K, plus the graphics card must also be overclocked, both must be super-exceeded, and the power supply is recommended for you to use a gold power supply rated at 600W+.

Personally, if you don't overclock, you can replace the CPU, replace it with E3 for less money, replace the motherboard with the B85 big board, and replace the power supply with the two I said.

If you want to play overclocking, change the CPU to 4690K or 4790K, the motherboard will remain the same, the memory will be changed to the Corsair 2400 series, and the others will remain the same.

Memory can be added. Other accessories can also be upgraded, but they need to be replaced, such as CPUs and graphics cards.

What does it mean? Upgrade win7 ah or upgrade the computer.

Upgrade 7 is stress-free.

You're going to change win7.,Can be changed.,It's best to 32-bit win7,

If you are short of money to play games, you can change the graphics card, don't upgrade if you don't have any special requirements, it's not cost-effective, and it's not expensive to buy a new machine.
