Built So I Can Upgrade
This last computer I built was based around the memory modules I had at hand. The motherboard and CPU in my previous computer was fried in a power surge, but not the memory which was two DDR2 modules, 2 gigs each. So I had to choose a motherboard that would accept the memory. After a lot of research I decided to go with an Asus motherboard that was on sale for fifty nine dollars and a new 2.6 Ghz Pentium Dual Core processor that was also on sale for fifty nine dollars. One of the things I like about the motherboard is that the CPU can be upgraded to a 3.16 Ghz, which is a little out of my range as far as money goes, for now anyway.
After thinking about it I decided to go high quality with the power supply and video graphics cards. There's no way I was going to use the power supply from my old computer, even if it tested good, because if it was damaged it could also damage the new parts I bought. So I went with the 650 watt Corsair psu. I got it for a little over a hundred dollars and am very impressed with it. The number of cables that are on it leaves a of room for upgrades in the future. And also the reputation Corsair has for quality makes me feel confident about this choice.
The video graphics card I chose was the Nvidia GeForce GTS 250 1028MB. It has a clock speed of 738 MHz and a 256 bit memory bus. It also has 1 Gigs of DDR3 memory. I thought this was a good choice because it requires a 450 watt power supply and I have a 650 watt psu. The price was $149.99 which I thought was a good mid-range price for the quality it has.
My old case was a little small so I found myself wanting a little more quality and decided to buy an Antec 900 gaming case which cost me $150 dollars. This case is very impressive with 4 fans to keep everything cool and an optional fifth fan which I'll probably get.
So that was my methodology in putting this computer together. I based my choices on the memory I already had and went cheap with the motherboard and cpu. However the power supply, video card and case can be used well into the future I believe when I'm ready for another upgrade.
