I see there are three Intel boards at https://www.reddit.com/r/PCMasterRace/wiki/builds today.
These are used by thousands for builds and often good to fine choices.
1. I used to get the i5. At shop and home we just get the i7 now.
2. See my comments about boards from PCMR. Since motherboards rarely give us any speed or other increases I tend to go with the crowd here. I have yet to buy a board for RGB Lights or looks.
3. Should have no speed affect. Go with price.
4. Cases are personal choices. Go with which you like best.
Frankly I skip the LED RAM, go plain and double the size of the SSD.
For now I avoid Seagate drives. As to the PSU, I see it's a single rail +12V which keeps new builders out of trouble and avoids discussions about moving loads among rails. You can check reviews on the model.
I am going to build my first PC and plan to use it mainly for gaming.
What do you think about the following configuration: https://pcpartpicker.com/list/rhQQq4
I also have a list of questions/explanations based on that:
1. I want to build it around Intel architecture (personal preferance). I know that an i5 is good enough for gaming but I want an i7 because I saw it's better for over full hd resolution even in games and I might want to learn Photoshop one day...
2. What motherboard do you think is the best? GIGABYTE Z370P-D3 or MSI Z370-A PRO?
3. What do you think about the RAM? Is it ok the 3000 frequency or should I buy a 3200 for 15$ - is it worth it?
4. What case do you think is the best? Corsair Carbide 270R Black or SilentiumPC Gladius M35W Pure Black?
* The real HDD is WD Blue 1TB SATA-III 7200 RPM 64MB . I cannot find it on PcPartPicker.
* The real power supply is Segotep GP Series 500W, 80 PLUS GOLD. I cannot find it on PcPartPicker.
Thank you a lot!
