i just got the gigabyte geforce gtx 780. it works GREAT, but just for fun i got a gts 450 from a buddy of mine and i wanted to see if physx turned on high would run better with using the 450 as a dedicated card. so far ive only seen a 2-3 FPS increase. is this because the 450 is a bad card or is it because the 780 is so good.
ive tested this with the batman arkham city benchmark, darkvoid benchmark and fluidmark. there the only things i have to test with and if anyone knows something else i can use please tell me.
ive always used ati/amd cards in the past so i dont know anything about physx so if i sound like i dont know what im talking about its because i dont. (also why im doing this :) )
my specs;
cpu amd8320
gpu gtx780 with the gts 450 as a dedicated physx card
8gb ddr3 1600 RAM
gigabyte 990fxa-ud3 motherboard
750 watt thermaltake power supply
heres my results;
batman settings were anti-aliasing; NVIDIA 32X CSAA DIRECTX 11;MVSS AND HBAO DIRECTX11 TESSELLATION; HIGH DETAIL LEVEL; VERY HIGH MOTION BLUR; NO PHYSX; HIGH everything else was either on high or set to yes.
with 450 dedicated physx card
min; 26 max; 88 avg;52
with the 780 alone
min; 13 max; 86 avg; 49
darkvoid settings were at the highest however for some weird reason it wouldnt let me turn the physx setting any higher than low.
with 450 dedicated physx card
min; 68.11 avg. 91.17
with the 780 alone
min; 67.52 avg; 88.72
fluid mark settings were using the 1080 preset
with the 450 dedicated physx card
score; 3040points, 50FPS(GPU ghysx)
FPS min; 50 max; 51
the 780 alone
score; 3332 points, 55FPS (GPU PhysX)
FPS min;54, max; 57
I ran all these test 3 times and took an average.
it really doesnt seem that haveing a dedicated physx card is necassary in my case but if anyone can give me some advice on some other tools i can use to test it with that would be awesome. also if someone could tell me where to download the metro benchmark, and the borderlands 2 benchmark if they have one that would be cool since i dont own these games yet. if theres any other tests you guys would like me to run just for fun i'll try to just to see what this baby can do!
