Megadeth these are the downfalls of the products you just mentioned.
The DFI board is a gamble because I heard they are not all the same, performance wise. Some are AWESOME and some are duds apparently.
the geforce 6xxx series are good performers especially at humongous resolutions and Doom 3. If you want to save $100 buy a radeon 9700pro and play games at 1024x768 at almost the same smooth quality!
As fore the volcano it will cool very well and give you a better overclock but for 50 more MHz your computer will sound like a vacuum cleaner while ur playing solitaire!
