No performance increase ?

Just installed my second 5870 and put them both in crossfire.

I have the HIS HD 5870 iCoolerV in the top PCIe x16 slot and the XFX card that I JUST bought (another HD 5870 with the same amount of RAM) in the PCIe x16 slot underneath.

They are connected together with a bridge and Crossfire is enabled. Anyway, I ran a benchmark on the single XFX Radeon HD 5870 by itself and got a 3dmark06 score of 19000 something. I then ran the test again (but this time with the HIS HD 5870 WITH the XFX HD 5870 in crossfire) and got a result of 19,000 something.

So almost exactly the same. Other than plug both cards in, reinstall graphics drivers and enable CrossfireX in the cataylst control center...I havent done anything to either of the cards.

Really disappointed. : ( help ?
 
try running another benchmark or game to see if it's just a problem with that app.
Also, check you have the latest crossfire profiles installed.

Crossfire Enabled

Aaaaaaaaaah.

Min FPS: 29.7
Max FPS: 70.4

Gameplay

However...bad company 2 still has some lag. The same with black ops. Quite a lot objects are still loading in front of me when I'm running towards them. Is this usual ?

Thats the game loading textures from the HDD, the only way to really get rid of that is to get an SSD.
 
Why is it everytime a new 3DMark comes out the old one is touted as being a CPU orientated benchmark and useless? Surley it wasn't a problem when it was the latest and greatest? New hardware platforms come out and the score don't go up as much as expected so it's deemed as outdated? Maybe the hardware just isn't as fast as other software suggests?

Your CPU is fine, it's just you need to run things that are GPU limited like modern games and heaven/3dmark 11

When I was doing a decent amount of benchmarking on my 5870 Crossfire, I saw gains upto CPU speeds of 4.2GHZ.

3DMark 06 only supports 4 threads for a start, so it's already got a CPU limitation. And the tests aren't very graphically intensive now for these GPU's. While the GPU's eat it alive, the CPU becomes the bottleneck.

CPU bottlenecked massively.

Thats a massive drama queen moment, while i agree o/c the cpu will get you a better score in say vantage it's not a lot and fps in games less so. I did a bench with i7 stock and i7 4.4 somewhere on here ages ago there was defo a increase in benching but "massive bottleneck" :rolleyes:

Isn't it more to do with the clipping distance that is set up on the game? Seeing as a large chunk of the code is designed to work on consoles too maybe it's a hangover from that. The reason I say this is that some objects 'pop up' on Bad Company 2 for me too and the game is installed on a Vertex 2E SSD. Usually only one or two barrels here and there and it looks more like a glitch when it happens to be honest.
