    185s with te K5000 really? That is incredibly slow isn't it? It Should be 4 times faster than the 560, but it's actually sightly slower?
    At worst it should be comparable to the 670, but it's slower than that as well.

    I'm guessing something else in the system is causing a bottleneck here.

    Sadly no....the K5000 is about 40% slower than the Quadro 5000 meaning that benchmark is dead on. Kepler performance is lacking so far and we all hope that change is on the way.

    But 670 is Kepler too, but it's not nearly that slow. That's why I was thinking it wasn't quite right.

    @David
    the current version of Bunkspeed is compiled with CUDA 4.2 or 5?
    I ask because in Vray-RT (cuda 5) the Quadro K5000 is 2,5 times faster than the Quadro 5000

    the version of iray we currently use is compiled against CUDA 4.2. I imagine a version that is compiled against CUDA 5 is right around the corner. Thanks for the info

    I am lucky to have access to some great workstations during normal business hours and we are currently getting some brand new dual 690 boxes within the next two weeks. BUT...every once and awhile I need to run something at home, usually as soon as the kids are in bed. For these occasions I have the Po' Boy Box. In other words, what's the biggest bang for the buck I can piece together out of an odd mix of 4 year old guts and some brand new pieces. This thing has to serve as CAD workstation for Proe and Alias, Video editing for school sports, games of all kinds, and all other kinds of abuse that a proper box shouldn't be exposed to
    Right now this consists of:
    Asus P5QL VM Mobo with an Intel Core2 Quad Q8300 - no OC
    8 gig DDR2 ram
    Sata 2 Barracuda Drives
    600W Corsair PSU
    For graphics, I was running an EVGA gtx 550ti OC prior to Christmas...

    Thankfully Santa brought a brand new EVGA GTX 660ti FTW Sig2 for right around $280. I know what you are all going to say about the gimped 104 chips and how Fermi is so much better. Yes it is for a dedicated machine. I could have gotten a 570 card for around $250 but would have needed to go bigger on the PSU and for the other stuff this rig has to do, the 6 series made more of an impact.

    Here are the numbers that count:
    GTX 550 ti - Bunkspeed Graffiti benchmark 960x540 500 passes - 305 sec! really bad. RT @ 500 passes 1.66 FPS
    GTX 660 ti FTW sig 2 - 960x540 500 passes - 147 sec HUGE IMPROVEMENT RT @ 500 passes 3.42 FPS

    Huge bang for the buck on a really outdated system. I'll run the same tests on our 580, dual 590 and upcoming dual 690 boxes soon but in a way it's more satisfying to build a sleeper and get good numbers.

    Merry Christmas all,
    J

    First reference at work:
    Dell workstation
    Xeon X5670 @ 2.93GHZ
    12 GB ram
    GTX 680 2048
    Bunkspeed Graffiti benchmark 960x540 500 passes - 109 sec. RT @ 500 passes 4.75 FPS

    lele,
    What kind of FPS are you getting in RT with the two cards together? That Quadro must really have a slow clock. That card doesn't even have active cooling, correct?
    The Asus number doesn't surprise me knowing it could be clocked faster or maybe your machine has PCI 16 x3 vs. mine with PCI 16 x2.
