I've built loads of PCs over the years and they're not difficult but you need to be patient and get it right first time in terms of tidy cable runs etc. as your intention to sort that out later will never materialise. I'm not a gamer but have built two machines for gaming friends; one was on a good budget, the other was of the opinion 'cost is of no importance, build me the fastest thing you can.' This turned out very expensive and the delays getting soe very high-end components can be frustrating. Added to this, water cooling adds complexity and limits case choice. As other have stated, if you're building a true gaming PC you need to decide the following (in roughly this order):
- Do you want/need water cooling? If you do, it will add cost, time and complexity. For what follows I'll assume you decide against this.
- Determine which processor you want to use as the socket type will drive motherboard compatibility. Get the most powerful processor you can afford within reason. I'd be looking at an
Intel Core i7 10700 as a minimum and ideally something like the
Intel Core i9 10850. If you went for the latter this means you'll need a socket LGA 1200 motherboard.
- Select a motherboard and don't skimp but here you need one that has the features you feel you need and most will. Here, generally, you get what you pay for but no need to go mad.
- Select RAM; buy 32GB as two modules; this should be plenty. If the motherboard you select has 4 RAM slots you can expand later if required but it's unlikely you'd need to.
- Graphics Card - buy a good one. I'm not a gamer but have a powerful one to drive an ultra-wide 49" monitor.
- Monitors. Have a look at 49" Ultra-wide monitors that are they equivalent of 2 x 27" monitors and, IMHO, only consider 5120 x 1440 e.g.
THIS (which is what I purchased). More expensive than 2 x 27" monitors but simply brilliant. you could obviously go 2 x 27" initially and upgrade later after your wallet has recovered.
Let us know what you decide and how it goes. If you have further questions I'm happy to assist if I can.
