1. The video card
The video card is probably the main part of a gaming computer. Many lower priced off-the-shelf systems use integrated video cards. What this implies is that the graphics are handled by a chip that’s integrated into the motherboard. You could wonder what the difference is. To attempt to use a built-in graphics solution for a gaming computer is similar to putting only a little 4 cylinder engine in a Corvette. It may look great nevertheless the performance will probably be extremely disappointing.

It isn’t overly expensive however it will provide you with great performance. Other video cards with similar performance are the Nvidia GTX 280, GTX 285, and the GTX 470. There are many other available choices at verying price ranges so do a little research. When someone tries to provide some type of computer with an integrated or on-board graphics solution you’re getting ripped off. Shop somewhere else.
2. The CPU
As mentioned, don’t make your decision based solely on the CPU. With that being said it is very important that we get a PC with a CPU that won’t bottleneck our video card. We don’t want a budget processor. Choose a Core i5 or Core i7 processor if you should be buying an Intel based machine. For AMD platforms choose a Phenom II X3 or X4 processor.
3. Power Supply
If you have a dinky power supply you won’t have sufficient juice to perform your components. Outward indications of an inadequate power supply include your personal computer randomly turning off and lag during game play. Issues stemming from power supplies in many cases are misdiagnosed as other problems. Make sure your computer includes a big enough power supply. You’ll find power supply calculators online. Enter your components and it’ll calculate simply how much power you need. Bear in mind that not absolutely all power supplies are created equal. Be sure you purchase from a good manufacturer such as Antec, Corsair, Silverstone, etc.
If you really desire to be sure you obtain the absolute most computer for your hard earned money you might want to think about building your own gaming computer. It’s actually not very difficult and it lets you select all of your components. Among the difficulties with off the shelf computers is that you’ve no means of knowing what they use for a number of the components.
