I’m looking to build a new computer for gaming purpose. I think any gaming system should consider following fast components :)
=> A fast Intel or AMD dual core processor / CPU (Intel core 2 extreme, is the latest in ass-kicking technology)
=> 1GB dual channel DDR2 SDRAM at 800MHz
=> 512 MB Graphics card from ATI or NVIDIA (look for GeForce 8600 / 8800)
=> Good sound card (on board sound cards are quite good these days so you can same some money)
=> SATA 3.0 Gb/s hard disk (500G)
=> And most important good cabinet / chassis with 2 cooling fans with enough power supply
Dell / Alienware offers top of the line gaming and multimedia computer. Personally I prefer to build my own computer :)
