eBay and other used stuff shops really protect the buyer to the point of being really unfair to the seller.
No, you don’t remember correctly.
This may be of your interest then.
You will be able to save some good 300-400€.

Gpu rendering is much slower on GPU in Blender 2.70 
The same scene took only 58 sec in version 2.69…

That is interesting indeed. Didn`t expect that. Though vRAM is not cheap but there should be considerable savings.
Just to add variables…

Trivial differences… More interested in higher level support like; cage baking to multiple map types.
does anyone know blender-related data about the tesla series? is it even faster than the titan? I could get my hands on a Tesla S2050… but I must be sure this thing works fine with cycles first.
//edit
found the answer - should have searched the forum first 
Hi payne, the Tesla,/Quadro cards are slower as the GTX cards with the same core.
They are down clocked, reduced to work 24/7 in Pro environment and are very expensive.
Cycles work with fine them.
Cheers, mib.
oi wheres my cards xD
