My choices for a cheap build. In my consideration i build a computer to last me 6 months and then i sell it. I do try to build a computer that other people would want to buy so i keep it simple and buy the fastest/cheapest i can afford at that time.
So, heres what i think is fastest/cheapest.
AMD X2 3800http://www.newegg.co...N82E16819103735
BFG GeForce 7600GT 256MBhttp://www.newegg.co...N82E16814143049
Total cost (after rebate)
Cost your system parts were.
Slightly more but a much easier sell in 6 months than yours. By the way Newegg has sold out on your vidoe card already. So adding in case( the $34 one)memory, dvd drive, hard drive, and a $90 Power supply to either one you have either $526 for yours or $607 for mine. And i think in 6 months you will still be able to get at least $350 out of this computer( if not more). Well worth it for a interim computer. I say this because either you do not have the money to build what you want or you are planning on waiting until prices settle down on the Core2 Duo cpu's to built a much better computer later.
If it is a money thing it is still better to spend a little bit more so resale value will be better. Otherwise do not build a cheap computer at all. I build to a price because every computer i build i eventually sell. So i build for the best bang for the buck but with the idea it is to be sold soon.So i end up build a middle ground computer with some good quality parts. I have a group of people that when they go looking for a new computer they look me up to see what i have before even going looking on the net.
If its just the high prices on the conroe system, i would make do with a used computer if necessary until i could afford the system i want. I frustrated myself many times years ago because i didn't like prices of computers i wanted to build so i did without or made do with a cheap build that i really was not happy with.
