Vray or Vray RT GPU for final renders?

[ilter]

I am about to buy a workstation with the following specs; Dual Xeon X5680, 12 GB DDR3 ECC RDRAM, 2 x Corsair F40 40GB SSD RAID 0, 1TB SATA II NS, QUADRO 4000 GRAPHICS
My question is; does it worth it to spend more bucks on CPUs rather than Graphics card because Vray Final renders would be much more qualified compared to Vray RT final renders? Thank you for your answers.

RT does not produce final quality images so you have to decide if the additional preview speed is worth it to you. It may be worth waiting until the GPU version is released in December and then add a card at that time. By then I'm sure there will be a whole bunch of new and faster cards out. This is especially true for the lower cost gaming cards which tend to be obsolete after about 12 months.
