What is the best desktop specs for gaming?

I want to build a new desktop pc dedicated for gaming and dont know much about hardware i want to know which brand and model should i buy

These are the parts that i dont know what model to buy

1. motherboard

2. video card 512MB

3. Intel core 2 duo



but not too expensive|||You can go for Assus P5N MX motherboard it has inbuild 512 mb graphic card so you can save graphic card amount.|||A very good mother board is Gigabyte GA EP 45C DS3R or greater . The DQ6 is great and gigabyte boards come with easy tune over clocking facility.Video cards, Gainward ,Gigabyte, EVGA, ASUS any top brand with NVIDIA 9600 or 9800 chip-set and 512 MB, Some cards have DDR3 Memory but you have to shop around, i think Galaxy have some too. CPU intel E8400 core 2 duo or higher to lower end of Quad core. Choose a good brand and shop around for the best price, Oh PSU 550watt + depending on your system and games and kingston HyperX DDR2 1066 series RAM 4GB good value for money,

Check out the kingston web site and run XP OS. Do lots of research and have fun.|||High RAM



Excellent Graphic card



Good motherboard



These 3 are what you need to build a good gaming PC. |||You must use AMD Processors..the best thing I can recommend is AMD Athlon XP 3.0 Ghz..NVidia GeForce 8600GT video card..and also 2 GB RAM..That's all Thank You!!
