Hello,
I was planning to buy the new topmodel of the mac pro line, but cause of the price tag and the little rendering speed difference, I would like to know what the options are to pimp my current mac. without any hacks and no I don’t want a pc 
I heard about upgrading the graphics card with the GTX680 but this doesn’t seem available anymore, also I would like to replace my old firewire drobo system with something faster as the Pegasus systems but these have only thunderbolt ports, should I go for the Drobo 5d then which has more ports then only thunderbolt, or should I upgrade my internal storage? I am a bit lost here, this is all to technical for me 
basically it comes down to this:
C4D viewport too slow
Lightroom too slow loading 50mb pics from drobo system.
Vray faster rendering
Mac Pro Mid 2010 / 5.1
Processor: 2 x 2,93 GHz 6-Core Intel Xeon
Memory: 16 GB 1333 MHz DDR3 ECC
Graphics: ATI Radeon HD 5770 1024 MB
Storage: 1TB Normal HD + 500GB SSD
- External DROBO (firewire)
Thanks!
