so i have a vostro 200, had it for a while, recently bought a 400 watt power supply for my 8800gt (dont laugh i got it for $80) i know im stupid should have spent more on the power supply for a 600watt...to late. Anyways im running an e2140 1.6ghz overclocked at 2.6 1m cache its really old. i was looking at the e6700, on ebay for $100, will i notice a big difference in 3dmark 06 becuase im getting just over 10 000 now. Any other cheaper processor's to get that are good for overclocking? BTW i have to do the BSEL pin mod becuase of the stupid dell motherboard.
