Build a Kick-Ass $500 Gaming PC, Play Crysis at 40FPS!
9. We Need Power!
There’s no other way to fire up your newly assembled computer without adding some power to your parts. This is the home stretch of the PC building process; just remember not to leave any components unplugged.

Make sure that the PSU is not plugged into a wall socket and that the switch on the power supply is set to “—“, meaning it’s off. Grab the 24-pin connection from the power supply and connect it to the motherboard’s power connector, located to the right of the memory slots. Pop it into place and gently tug to make sure it’s locked in securely.
Locate the four-pin ATX power connecter and hook it up to its appropriate socket; this will supply supplemental power to the processor.

We ran into a bit of an issue when connecting power to our GPU. The power supply we received only had one PCI-E power cable, so we hooked up an adapter to convert a 4-pin molex cord into the second six-pin PCI-E cable that the Radeon 4870 needs.
Lastly, plug in the thin SATA power cables into the hard drive and the optical drive. These are the flat power cables that resemble longer versions of the SATA data cable.
10. Operate Your System
Now that you’re finished building your PC, you’ll need to install an operating system. If you want to use Windows XP and you don’t have an old disc lying around, you can purchase an OEM version off of Newegg for $100.
Since we didn’t factor in the price for the OS, the choice is yours; XP, Vista, or even the readily available Windows 7 Beta. We chose to use an old XP key from a previous build to install and run our benchmarks, which we believe is what most budget-minded builders would do.
Check the following before you decide to install an operating system:
- All the parts are properly seated
- All the cables are in place
- Double check that the front panel connections are correct
- Plug in the monitor, keyboard, and mouse
- Plug in the power cord to the PSU
- Flip the PSU switch to the on position
When everything is read to go, press the power and voila! Hit the DEL key during startup to be taken to the BIOS screen.
Go to Advanced BIOS Features – Boot sequence and select the CD/DCD optical drive as your first boot device. Press ESC to go back and disable the Full Screen Logo Display to enable Quick Booting and increase your boot time. Once you’ve made the necessary changes, press F10 and select Yes. The PC will restart and during reboot, insert your Windows CD of choice into the optical drive and setup will begin. Follow the instructions to successfully install Windows.
After Windows has installed, head back to the BIOS set up and change the boot sequence to set it up so that the hard drive boots first and then the optical drive. Find the manufacturer’s CD that came with your MOBO and be sure to install all the appropriate drivers, as well as the drivers that came with your GPU.

Hooray! Now you’re all finished assembling this PC. That wasn’t so hard, now was it?

Our current desktop Zero Point test bed consists of a quad-core 2.66GHz Intel Core 2 Quad Q6700, 2GB of Corsair DDR2/800 RAM on an EVGA 680 SLI motherboard. We run two EVGA GeForce 8800 GTX cards in SLI mode, Western Digital 150GB Raptor and 500GB Caviar hard drives, LG GGC-H20L, Sound Blaster X-Fi, and PC Power and Cooling Silencer 750 Quad. OS is Windows Vista Home Premium 64-bit.
*Crysis would not run in"Very High" quality settings in this system build, since we were using Windows XP, which does not support DirectX 10.

Performance Analysis
We put our lean and mean $500 gaming rig up against our standard zero point machine to compare its performance against a rig that costs three times as much (when we first built it). The zero point system, equipped with a Core 2 Quad and a Velociraptor edged out our substantially slower turtle in nearly every race. Premier Pro tests showed a 4 and a half minute difference and with Photoshop we only had a 14 second difference. Photodex ProShow Producer showed only a 5 second difference while MainConcept Reference showed the true power of four cores, citing a 17-minute difference from our zero point. Still, the $500 PC did better than average in our tests -- definitely better than a comparably priced notebook -- and proves to be a really decent and affordable desktop computer.
We had some high expectations in the gaming department from our budget system, especially compared to the weak scores our last $500 PC delivered two years ago. Our pick of a 4870 graphics card came through when the lean machine delivered 122 frames per second in Unreal Tournament III, 30 frames per second more than the dual-8800 GTX-equipped zero point.
The big test, of course was Crysis, which is still the most GPU-intensive PC game. We ran our Crysis tests at three different resolutions: 1920x1200, 1680x1280, and 1280x1024; each one gave us a smooth picture and was void of any choppiness. At 1280x1024, the standard resolution for most 19" monitors, Crysis ran at over 44 frames per second -- an impressive number that's more than playable. Even at 1900x1200, Crysis didn't stutter and pushed out 36fps. Not bad at all!
However, we could only run the benchmarks at a DX9 High detail settings in Windows XP, as opposed to Very High with DirectX 10, which is only available on a Vista machine. This is why we’ve labeled it ”WNR” (Would Not Run) on our zero point comparison benchmark chart. But even with that caveat, we believe that most people who are building and gaming on a $500 PC will be using Windows XP, and on monitors that probably won't run higher than 1680x1050 resolution. And with those settings, this rig is nothing to scoff at. If you're a hardcore gamer who demands nothing less than DX10 gaming on "Very High" detail, you probably aren't building a sub $800 machine.
It is clear that there is a noticeable performance difference between our budget system and our zero point, but if you’re a budget-constrained gamer who wants to test the waters with an affordable system, and still be able to do everyday tasks—like edit photos, video, and run more than a few processes at a time—this $500 PC is a strong bet.
