Power Consumption And Temperatures
Power-saving features remain enabled on both stock configurations, as well as this quarter's overclocked $800 PC. As I tweaked the FX-6300’s clock rates last quarter, I turned those features off for greater stability and performance consistency.
The $800 rig’s Ivy Bridge-based Core i5 sips less power at idle and under load, but its beefier Radeon R9 280X graphics card pushes consumption higher in gaming environments.
We know there are folks who will worry that Gigabyte recommends a 600 W power supply or more to support its Radeon R9 280X. But keep in mind that (factoring in efficiency) the peak output pulled from our selection under full load remained under 300 W. EVGA's 500 W supply packs plenty of reserve power in its relatively large 40 A, +12 V rail.
Both boxed coolers are adequate for our mild overclocking endeavors, though Intel’s solution is quieter. If you live somewhere warm, consider a more elegant heat sink and fan combination, particularly if you plan to overclock.
Gigabyte’s three-fan cooler peaked at 79% under load, making my $800 PC noisier during gaming marathons. It's also worth mentioning that I occasionally heard mild coil whine while gaming, which I suspect came from the graphics card. It wasn’t frequent or loud, but I consider that squealing sound to be very distracting.
Not all countries have good internet infrastructure. If that wasn't the case Microsoft wouldn't have to reverse its policies on the X1. Another thing is retail game DVDs costs very less in my country. For example, Bioshock Infinite costs only 15.97$ at launch date. If I were to buy it through Steam at launch date it would have cost me 59.99$
I know that the writers of "best CPUs" for the money always make a huge fuss about how "oh, you save 7W (or however much it is) by not having the on-board graphics", but I still think it's worth keeping, for if your discrete card gives out on you. My PC buggered up installing my graphics drivers once, and if it weren't for my intel "backup" GPU, my rig would have been bricked.
For us, both were available from Newegg at a $10 difference. Either is fine. I chose the -3350P back for the Q1 $600 Gaming PC, and it's OC was limited to 3.5-3.7 GHz with this same Z75 Pro3 mobo. But I actually prefer the -3470 at these prices for reasons stated in the text (higher clocks and backup HD 2500 graphics). It fit in under budget, and its higher Turbo limit provide a 300 MHz boost across the board (3.8-4.0 GHz) when overclocking. That right there is worth $10 in an SBM where value equals a straight bang for buck calculation.
My own thoughts on this one are mixed. I like to see the challenge of a lower budget. This $800 PC was quite good, however. With the focus on gaming this SBM cycle, this one looks like a shoe-in for value winner. I don't see what two or three times the budget will buy that can offer similar multiples of performance, especially that will be visible in actual use.
That said, for my own uses, I'd take the "High" to "Max" settings in my games that a GTX650Ti Boost would offer, and put the balance into a SSD.
I currently just built a "budget" machine for my son which ended up close to $850. That build was using an Asus M5A78L-M/USB3 Micro ATX AM3+ motherboard, AMD FX-6300 3.5GHz to (O.C. to 4.3GHz @ 38 C), w/ an Enermax ETS-T40-TB 86.7 CFM CPU Cooler.
What I wanted had to be tempered with what I could squeeze into the budget so a new Asus Radeon R7 260X 2GB Video Card was put in for now. A WD Caviar (Blue) 1TB drive was put in for storage, G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory and a Corsair CX 500W 80+ Bronze Certified Semi-Modular ATX Power Supply to make it all run. Windows 8.1 was installed and the case is a nice looking Corsair 350D case.
My working theory is this rig will run well now and a new video card, better CPU cooler with a faster stronger CPU and an SSD down the road are all manageable upgrades that could keep this machine running good, playable frame rates for several years down the road.
There is always more than one way to skin a cat and to me this was the least amount I would build with.
