I came up with the build below using cyberpowerpc.com. I'm not a hardware expert by any stretch, particularly when it comes to gaming components, and need some advice. What do you think of the build? Am I overweight one set of components at the expense of another? I am OK with the price but probably can't go any higher, so extras will likely require a tradeoff. Also, I'm not thrilled about building instead of buying pre-built but could be swayed if the cost advantage was sizeable. What would you expect...$100? $200?
Wrong section really. I'll try to fire through some of the questions.
Firstly, you will save a fairly hefty sum by self building. If you aren't up for it, that's fine, but it will cost you a lot more. If you were talking about an entry level system, then buying isn't so bad because the margins are much smaller, but at the high end you can be talking hundreds of dollars.
The build is fine enough, but there's a few quirks.
For a solely gaming machine, and i7 has little benefit over an i5.
16Gb of ram is overkill unless you have a specific purpose for it.
A GTX660 is a solid graphics card and fine for 1080P gaming, but if you are spending that much on a gaming machine, you probably want a higher % of your budget to go into graphics, it's where you get the bang-for-buck really.
That PSU is ludicrous. A GTX660 and i7 can run absolutely fine on a good 450W PSU.
This is a similar build but slightly refocused. I7 to i5, 16Gb of 1866Mhz ram to 8Gb of 1600Mhz ram, monster CPU cooler, sensible high quality modular PSU and a better graphics card.
There's obviously a few things missing, but it gives you a rough idea of the price difference. PCPartPicker part list / Price breakdown by merchant / Benchmarks
