Forget it. Half the reason people are getting such high scores in 3dmark, etc are because these chips are so overclockable (1.6A @ 2.1-2.5 GHz, 1.8A @ 2.1-2.5 GHz, etc...). With that Dell there is no overclocking whatsoever, so you are stuck at 2 GHz (much slower than a 1.6A @ 2.13 which has a 133 MHz FSB and 133 MHz memory clock). You'd have to replace the motherboard in order to actually get the speed benefit from that (overclocked) 2.0a. Wait until they come out with faster (2.4-2.6 GHz) CPU's that aren't so overpriced like the 2.0a is right now then upgrade.
