Would this Upgrade be Worth it ???

[Luke2]

Hello, I am vaguely thinking about making the CPU/MOBO/RAM upgrade for my custom rig.
This is my current setup

MOBO - BIOSTAR TForce TP45HP LGA 775 http://www.newegg.com/Product/Produc...82E16813138123

CPU - Intel Core 2 Quad Q9550 Yorkfield 2.83GHz http://www.newegg.com/Product/Produc...82E16819115041
OC'ed to ~3.3

RAM - CORSAIR XMS2 DHX 4GB http://www.newegg.com/Product/Produc...82E16820145194

GPU - Radeon HD 4870 X2 2GB http://www.newegg.com/Product/Produc...82E16814129114

All powered by ENERMAX INFINITI 720W http://www.newegg.com/Product/Produc...82E16817194021

Now, the upgrades would be following

CPU - Intel Core i7-950 Bloomfield 3.06GHz http://www.newegg.com/Product/Produc...82E16819115211

MOBO - ASUS P6T SE LGA 1366 Intel X58 http://www.newegg.com/Product/Produc...82E16813131386

RAM - OCZ Platinum 4GB 240-Pin DDR3 SDRAM DDR3 2000(PC3 16000) http://www.newegg.com/Product/Produc...82E16820227310

My question is, would I see big leap performance-wise ? The PSU should still be able to give enough juice to all the new parts correct ? I know the 4870x2 might be bottlenecked by the current Q9550, therefore goin to the i7, would there be a significant difference ?
LAst but not least, please give me you true opinion on if this upgrade would be smart at this time considering technology comes and goes.
Thank You.

I don't really think that an i7-950 is ever a good choice, especially since you apparently feel comfortable with mild overclocking. I would personally go with a 920 instead. Also, I would go with the P6T Deluxe V2 instead of the SE, and generally you'll want a triple-channel kit (2x3GB) with an X58 build.

The PSU will be fine. It will definitely be an upgrade, but is it worth the $700 US (approx. cost of my proposed parts) to you? Personally, I wouldn't pay that much for that upgrade. i7's are good, but your machine is already pretty current.

I would wait till fall when the new socket, P55 chipset, and 8xx series i7's are out.

Thank you, I will definitely wait a bit.
Also thx for the valuable info on the triple channel kit, guess i need to upgrade my brain to date lol.

The P55 will be dual channel. Triple channel will be a X58 exclusive.
