Introduction

I talk to many people everyday about computers and how to fix them and I find that most people are still mystified by a computer and feel that messing with it in any way will break the computer instantly. Many of those people have not even moved their computer since the day it was set up for them. This is why, when something goes wrong, large retailers tend to charge ridiculous amount to fix even simple problems. And I do not like to see people get taken to the cleaners for something that was a five minute fix and cost them a fraction of the price that they paid for the computer. Or even just to upgrade components to get more mileage out of their PC, so that they don't have to run out and drop more money because of the advice of a retail clerk without knowing why they need to upgrade to a whole new computer.

Take a gamer for example, one that loves computer gaming but doesn't know how to upgrade his video card. I talk to many gamers who have not even cracked open their computer. Upgrading a video card is very simple and cost effective. You don't have to run and drop another three grand on a new computer just because you can't play that latest game. All you need to do is buy that new graphics card for that extra power at a fraction of the cost. But the first step to learning is to crack open that case and take a look inside, get familiar with the components. Read a how to build a PC article to learn how to install components and learn about them as well. I often say that a little bit of knowledge can save you a lot of time and money.

The Sapphire Radeon HD 4770 512MB GDDR5 is a great start for upgrading from that old card. The Radeon HD 4770 512MB GDDR5 by Sapphire is based on 40nm process technology. The HD 4770 512MB GDDR5 is very energy efficient, thanks to the new 40nm technology. The Radeon HD 4770 supports DirectX 10.1 for better performance during lighting and rendering in gameplay. The HD 4770 512MB is able to process physics in games, which your old card may not be able to, and the HD 4770 512MB GDDR5 can support HDMI output, with 7.1 digital surround sound, for an intense movie and gaming experience.
