I have two rigs I use for Blender.
One is a Mac Mini with a I7-3720QM and 8 gig of RAM (primary blending device)
The other a 1090T with 8 gig of RAM (overnight work horse for extended rendering)
When I run the BMW bench I turn in times of 02:20.07 on the Mac and 03:46.96 on the PC.
As I was digging through the spread sheet for the BMW bench I noticed that most of the 1090t scores were much slower than mine under Windows by 1 to 2 minutes. The reason I am pointing this out is because I am looking to upgrade the PC box and can not decide if I want to get a new CPU, MB combo or spend the same amount on a new video card.
I am currently running a HD6870 that I can not render from and with a relatively firm budget of $250ish my options are admittedly limited. I know I can get a 3gb 660ti for $255 but for $265 I can pick a FX 8350 / ASUS mobo combo. Or I could save a few buck and combo with a Gigabyte mobo and gain extra GPU scaling for the future.
So the question is whether it is worth buying a 660ti to get the PC rendering on GPU marginally faster than the Mac on CPU? I am basing this on the Tom’s Hardware benchmark of the 660ti using the BMW bench and coming in at 116 seconds compared to my Mac at 140 seconds. Or should I just upgrade the core of the PC and keep rolling like I have been?
