[SOLVED] CPU question on new build

Solution


At 1920x1080 you'll hit slightly higher FPS in a few games. At higher resolutions you likely won't see any differences. Long term the i7 will likely see a slightly longer useful life with gaming. Just as was seen with prior generations of i5 and i7.

As far as i5's go. Unless you get an 8600K/9600K with a Z370/390 motherboard and good heatsink. Then go ahead and overclock it. You aren't going to see much difference between i5 models. That extra $200 would be better spent on a much larger SSD so all your games can...
I wouldn't spend that much on a B360 when you can get a decent Z370 for the price. If performance is your ultimate goal. I would get a cheaper motherboard and faster CPU. Also you don't need to spend that much on the RAM. You can get similar RAM for a little less. I selected a better quality case and some decent case fans.

I suppose I should of mentioned it's mostly for gaming, I read in a couple places the i5 is the way to go as i7s don't give you that much more bang for your buck, but which i5 should I get, is the 8400 still that good?
 


At 1920x1080 you'll hit slightly higher FPS in a few games. At higher resolutions you likely won't see any differences. Long term the i7 will likely see a slightly longer useful life with gaming. Just as was seen with prior generations of i5 and i7.

Really at this price level. You'll just be nitpicking. Any of these options will do well gaming and variations will just make minor differences. Once you have something like a Ryzen 2600/i5-8400 or better, GTX 2070 or better, good quality PSU and 16GB RAM. I'd be thinking more along the lines of:
- What sort of expansion and ports does the motherboard offer?
- Size and speed of storage devices?
- Noise generated by cooling equipment?
- Aesthetics of the system?
- What will improve the gaming experience? (Mouse, Keyboard, Joystick, Monitor, Speakers)

How difficult are i5s to OC now, the one I have i5 750 Lynn field was very picky with voltages, I thought I cooked it once but the bios reset and it ran for another 5 years.
 


Most if not all motherboards which can overclock have auto OC utilities. They've gotten pretty good. If you want to optimize voltage to maximize the OC/minimize temps. You should still go through the BIOS. That's pretty easy too for basic overclocking. They still have power options for people really serious about overclocking. Which aren't necessary.

Although I've never overclocked the first gen i5/i7. Compared to Core 2 Duo and Core 2 Quad. A modern unlocked CPU and Motherboard are vastly simpler. My 3570K is a breeze. The utilities have only gotten better since then. Even GPU overclocking has gotten easy.

Edit: By the way. The AMD 3000 series is expected to debut at CES this week. You may want to hold off. Based on expected pricing and specs. These may be a killer deal for your uses.

I just waited for the new gpu lineup to come out, maybe I can wait for the cpu one too but what's the major difference between me buying a i5 8400, or the newest i5 9600, I'm probably ly going to have this computer for 8 years or so before upgrading anything major, unless something groundbreaking happens?
