HOW TO INSTALL PC GAMES USING DAEMON TOOLS
It is advisable that you download and install the latest version of Daemon Tools Pro which you can find in its website or at CNET. After having done this you should copy in to your hard disk the files indicated by mdf, mdo and I think the third one is mds. Then mount this image files by using Daemon Tools after which you can now install your pc games. However in some cases you still need a crack which you will be able to see after you have mounted and install these files. Just explore these files. There are also instances that you will be asked for a CD key and you wont find any CD key or CD key generator included in your disc. Fortunately you can look for the CD key of a particular pc game at YOUTUBE or other gaming websites.
PC GAMES (PART2)
If you want to play at resolutions of 1440 x 900 or a little bit higher then you would not need to spend a lot of bucks for a high end PC to be able to play games like Crysis which is a graphics demanding kind of game. I am emphasizing this because if you like to play at high resolutions perhaps at 1920 x 1080 at high definition, you will really need a high end video card. The rule is that the higher the resolution or the larger monitor then the faster the GPU that it will require.
Of course having a high end computer with a CPU like Intel i7 running at 3.0GHZ or more (overclocked) and a GPU like Nvidia GTX 285 or GTX 295 in SLI (be that in dual, triple, or quad configuration) would be the most ideal so you can play games at high settings and high resolutions and still achieve high frames rates per second.
An affordable computer with an Intel Core 2 Duo at 2.8GHZ and a Nvidia GTS 250 GPU will run most if not all current pc games in the market at a decent frame rate. The recommended system requirements of most pc games is that you should at least have an Intel Core 2 Duo 2.8 GHZ or better an Intel Core 2 Quad 2.83 GHZ and a 9800 GT graphics card. I am not familiar with AMD processors and ATI Radeon graphics card so I will just discuss Intel processors and Nvidia GPU. .
A Nvidia GTS 250 has almost the same technical specs with that of a Nvidia 9800 GTX+ however a GTS 250 is a little bit faster running with 128 stream processors, 738 core clock, 1100MHZ memory clock and 1836 shader. It has a lower power consumption and it is said to be an overclock version of a 9800GTX+.
Having multiple video cards requires an extensive cooling system and a more powerful PSU but if you do have money to spare then of course the best is having a high end computer. There are custom built gaming computers like those of Alienware and Digital Storm wherein you can even specify the hardware and software that you want to be included in your computer so long as you have the budget but if you have the skills or technical know how it would be cheaper to assemble your dream computer yourself.
POWER SUPPLY UNIT (PSU) and 12 VOLT RAIL
I have surfed the internet and have viewed many forums and websites in my quest to determine how one will be able to know the amperage on the 12 volt rail of a power supply unit of a computer. I found two ways of calculating the amps of PSU. First let me emphasize that I do not know which of these two methods is the correct one.
Add the amps indicated in each 12 volt rail, for example you have two 12 Volt Rails with 19 amps each then 2 x 19 = 38 amps.
See the label indicated in your PSU wherein in my case which is a 500 watts Raptor, it is indicated 384 watts with 19 amps on each 12 Volt Rail with a maximum of 500 watts. The computation is 384/12 = 32 amps.
Please take note that it is advisable to buy a branded PSU for it is more efficient and its power ratings are reliable.
Knowing the correct amperage of your PSU in its 12 volt rail is very important especially in the installation of graphics card. A faster or high end graphics card requires a higher wattage of power and amperes. If for example a Nvidia 9400GT only requires 350 watts and 18 amps on the 12 volt rail of a PSU however a 9600 GT requires 400 watts and 26 amps. If you install a Nvidia GTX 260 which requires 500 watts and 36 amps in a computer with a PSU of 500 watts but with an amps lower than 36 amps then the video card might not work properly. In addition high end graphics card require either a single or two six pin connector and in a GTX 295 it requires one six pin and one eight pin connector.
