Hey I just bought a 5870 today and used it in two games (oblivion and crysis warhead), and I'm getting worse performance than I did with my 4850. It has twice as many stream cores, ram, 5 times faster ram, and everything, but it's garbage! Windows experience index gives it 6.0, whereas my 4850 was 7.5. This is really bothering me, it doesnt seem like a 450$ upgrade!
I'm using the ccc 9.10, and nothing else has changed since my upgrade. I really need to fix this soon as the store I got it from only has a 14 day return policy so far this thing isn't worth it.

Did you actually test it in games? Windows experience index is pointlessly useless, and doesn't seem to work with the 5000 series properly.

If games are getting lower FPS, it might indeed be broken.

yes I did test it, it's around the exact same (when I take into account the hd pack in oblivion and different levels in crysis warhead) performance, I'm gonna test it with 3dmark vantage soon, that should give the most accurate results (plus itl have my old scores posted online to compare). is there a program that show how much graphics memory is being used? because dxdiag says it has 2800mb but my computer may be allocating system ram instead of graphics

Gpuz will give you detailed information about the card.

What are your system specs? Also, Subjective results are not that helpful.. 3dmark, or absolute FPS will tell us a lot more.

Reply to daedalus685

NM about the specs, your sig wasn't displaying for me for some reason.

Reply to daedalus685

OK, for a second I thought I found the problem, GPU-Z showed no RAM, but then it went all auto update and everything's in order...
I will run 3D Mark Vantage soon, also found a new benchmark that has dx11 support, looks cool

gonna try oblivion in the exact shape as I played before

EDIT: don't think oblivions a good tool to measure this with, a little outdated and it reads in the render report that my gpu cant handle things like water ripples and reflections

OK, under oblivion configured the same, I get about 60fps inside, sometimes drops to like 40 very quickly, and outside it's about 30 and frequently drops down to 12. the inside is the same performance, but outside my 4850 did a lot better never dropping below 40. this leads me to think its a memory issue, either that or oblivion isnt fit for judging, ill try fallout 3. also i dont think it will go above 60, as my refresh rate is 60 and v-sync is enabled (i think thats how it works

------------------------------

I suppose it is possible the memory on the card is simply not working, in large chunks. Though I can't say I've heard of that happening as usually the card would die with that much damage.

Anyway, try some other games, but there is a strong chance the card is broken.

Reply to daedalus685

Finally some results! fallout 3, although it doesn't go any higher than 60 (probably because of the v-sync thing), not that thats good news by itself as my 4850 could sustain at 60 as well, but while fallout 3 is open, its using only 500mb of system ram, as opposed to the 1gb it used before

------------------------------

Reply to pb7280

Vsync will cause the rates to plumit if the settings are high enough such that the card does not sustain 60. I would suggest conducting tests without Vsync if you want to see meaningful data.

Reply to daedalus685

will do running 3dmark right after this
also do you think i should install the asus drivers that it came with or just use ccc 9.10?

------------------------------

Reply to pb7280

ok 3dmark gave me 10828 cpu score and 6858 graphics score. also it didnt give me a total score for some reason it says n/a

ok playing oblivion without v sync bumps up the fps to about 70 inside and 25 out. the problem is either cpu or mem related i think. it stutters majorly everytime something is loaded in the back ground, which i think may be because of bad vram.

and google shows some guy got 11000 gpu score with a phenom 2 940 and his wasnt even oced.
but after a lot more googling apparently the 9.10 drivers a bad. ill try 9.9

EDIT: FIXED! it seems that 9.10 added a type of antialiasing called supersample and when i turned that down to adaptive aa i could play oblivion 60fps outside with vsync. two lags in 2 minutes but they seemed cpu intensive (the game has a lot of ai stuff going on) like an enemy dying from my sword that does 15 ice 15 fire 15 shock 20 drain health 30 wekness to magic 35 base all that and taking into account the enemys defense capabilities. looks like once the hexacore i9 comes out i may get on that im tired of being stomped on by intel procs
ill try crysis w tomo if it works good i wont reply again
