Hello folks!
I have a 2009 built PC which i use as a freelance for 3d sculpting, modelling and illustration.
CPU: Intel Core i7 920 D0 BOX, Quad Core, 2.66 GHz,
CU: Noctua CPU-Cooler NH-U12P SE2 - Sockel 1366/1156
MOBO: AsRock X58 Extreme, Intel X58, LGA1366, SLI, CFX
RAM: GeIL EVO ONE 6x2GB Kit, DDR3-1600, CL7-7-7-24@1
SSD: OCZ SSD Vertex 2 Extended Cap. 120GB, SATA-II,
HDD: WD VelociRaptor WD3000HLFS, 10’000rpm, 16MB, 30
HDD: Samsung HD103SJ, F3, 7200rpm, 32MB, 1TB, SATA-II
DVD: LG GH22NS, 22x DVD±R Brenner, SATA, schwarz
PSU: Corsair CMPSU-850HX, 850W, SLI/CF, ATX2.2/EPS
Case: Cooler Master RC-690-KKN1-GP, inkl. Mesh-Gitter
GPU: MSI GTX-275 Lightning (GT200b) 1792MB GDDR3, REMOVED
GPU: EVGA GTX780 SuperClocked
I changed my graphic unit 3 days ago, and i think i picked a good one… the 780 sits on the upper corner of the “sweetspot” on the “Bang per buck” curve, i believe.
Having always been a very unsecure person, I can not settle and i think i might have done a mistake. Many ramble about how the Titan Black is much better because of floating points. I dont even know what floating points: do i need them or not for Mudbox sculpting?
I have noticed that since i have plugged in the 780, the viewport is extremely smooth, which is great and just as i expected, but i see that the sculpting tools are not as fast as i tought they would be. What im wondering is, do the calculations of the brushes go to the GPU or to the CPU? In that case, it would seem my CPU might now be the bottleneck.
Question 1: did i pick a good GPU?
Question 2: Any toughts on how to proceed to improve performance? I have already overclocked my i7 920 to 3.7ghz…
thanks a lot for your answers and time
