Upgrade to Nvidia NVS 510 for 24/7 usage

[DeaconFrost]

I have a Dell tower that runs two NVS 510 cards, driving six 24" monitors and a 55" TV. Lately, it's been locking up, giving VIDEO_TDR_ERROR errors. I've done all the software fixes I can come up with, so I'm going to try replacing the cards. I assumed these were pretty high-end, but maybe I need to go higher. I need them to have quad outputs at least. What would be a worthwhile step up from these cards?

NVS cards have never been "powerhouses"...your GPU is the same as a GeForce GT 630 (GK 107)....it just supports 4 monitors.
An current upgrade (that is better performing, but still no powerhouse) would be a QUADRO P600

Thanks for the info. I have two Quadro P620s on the way.
