Single or dual socket Dual Socket 1366 Motherboard?

Hello all,

Am a VFX artist my main usage would be on aftereffects and some amount of 3dsmax and photoshop with sometimes on adobe premiere,but most of the time i would be working on after effects.I have done some R&D regarding the system.I would be working on HD resolution.

But i have read somewhere that instead of a highend GPU invest in i7 extreme and just take a basic GPU.But can i do that coz can't invest too much on both.

I need to buy within this week.
