I'm considering upgrading my Intel Core 2 Extreme QX9650 processor, Gigabyte GA-EP45-DS3R MoBo, and 8GB of 800MHz ddr2 ram to a Intel Core i7 920 processor, GA-EX58-UD5 MoBo, and 6GB of 1600MHz ddr3 ram. This upgrade would cost around $100 after selling all my old parts. So, is this a worthy upgrade? Considering the i7 proc I'm looking at is the cheepest of it's class, and my current proc is the extreme, so top of it's class, not to mension it costs $1000 new vs. the i7 which is only $280 or so. Basically I'll I'm asking is this upgrade is going to be worth it as far as speed? BTW I'm running this as a hackintosh, not that would matter in this question.
