Upgrade CPU query, or switch to I7

[Serial45]

Just debating on upgrading my system guys.
I will mostly be gaming and playing games in high resolutions (2560*1600 mostly).

Will be using photoshop from time to time as well.

Considering just upgrading my CPU to this.
Intel Core 2 Quad Q9650 LGA775 'Yorkfield' 3.0GHz 12MB-cache (1333FSB) Processor - Retail

Or thinking of selling my exisiting CPU / Board / Memory (in sig) and getting an I7 setup :

I7 2.66ghz

Corsair 6GB DDR3 Dominator PC3-14400C9 1866MHz (3x2GB) Triple Channel DDR3 (TR3X6G1866C9DF)

Gigabyte EX58-UD3R Intel X58 (Socket 1366) PCI-Express DDR3 Motherboard

Or maybe get a better motherboard, toying with the idea at present.
Will cost me around £700 to upgrade.

Should I go for it, what real benefits will I see? I figure if i get a couple of hundred for my bits I have atm, will take the sting out of the I7 option.

Is it really worth upgrading at all? It doesn't seem to me you would gain that much, especially not with the q9650 option...

Maybe not, just debating it overall, after reading into it a little more over the past 30 mins or so apparently DDR3 memory really isn't that big of a leap.

Just felt the need to as I haven't changed my CPU / Board for over 2 years.

Well i suppose if you have money to burn then go for the i7, but you won't be blown away by the difference lol
