GTX 570 with a dedicated physx card - GTS 450

[CRAZYCAP]

Hi Guys

Thought I'd share some information with about running a GTS 450 alongside a GTX 570 as a dedicated physx card. I had one lying around and tested it in my gigabyte z68x-ud3r-b3 and the scores in every benchmark were lower. The reason the overall score was lower was because it heavily impacted my CPU score.

With the dedicated physx card I scored 26415 and without 30129.

I think the GTS 450 is too weak for a physx card in comparison to letting the GTX do the physx processing by itself.

Anyone had similiar issues and does anyone know where the balance of performance is. I am wondering if a 550 or 560 would yield a better result.

what would probably give you a truer a result would be to try it on a game that makes use of a dedicated Physx cards (Batman AA is a good example) rather than running a cpu bench test.

when i upgraded from a GTX275 for a 570, i tried my Gtx275 as a Phyxs card and ran the Batman AA Benchmark with and with the 275 doing the physx, the result was the min frame rates were about the same, the average was about 10fps better and the max fps was about 20fps higher. so i did get slighty better results but the performance gain to watts consumed(and moneyt spent on the card), i would say the returns are not really worth it (doesnt mean i wont be trying it with Batman:AC)

TBH i dont think you should throw more money at a another card for Physx as youre not gonna get bang for you buck returns on it not only just in performance, but in terms that i dont think there are that many games that make use of a dedicated physx. The 570 is more than competent card for running most games on the "tooty fruity" settings.

yeah agree mate. What I'll eventually end up doing is going SLI goodness with another 570. I also read that with the latest nvidia drivers they have dropped support for dedicated physx cards.
