New Video card ddr3 for AC

Hello Racers! I want to ask your advice for a video card, I now have an ATI radeon HD 5800 series and I'm well on many games, but now I want to take a new card, I would spend about 200 euro and must be ddr3 .... what do you advise me to run just fine on AC ... thanks to all!

 

You have either a 5850 or 5870 which has GDDR5 memory, why would you want to downgrade to GDDR3?

 

Can't seem to edit previous post, but i would suggest maybe a R9 270x? it's a couple $$ more that your budget.

I would get an Geforce GTX 770 if you can afford 60-70 EUR more (260 € cheapest GTX 770 in Germany).

If you like AMD more get the R9 280X. Mantle is coming soon so maybe the card get's a nice boost. (Open Source but Intel/nVidia had no interest in this new API but who knows maybe it runs on Geforce cards soon as well.)

You should be able to play AC with max details with either card (when they fix early build problems of course).

 

Go with Nvidia, I bought Gigabyte R9 280X and many games run slow. In AC I need to turn off vsync in order to get more fps and full GPU usage, so have many problems with AMD...

 

At the moment there are two possibilities

amd r9 280x -> 280x is the new labled 7970 ghz edition
nvidia 770gtx
​

amd

pros:
more power for invested money
able to run 1080p with decent frames and quality
3gb vram
performs better on higher resolutions

cons:
much more power consumption (500~550w psu requiered)
at the moment less fps than a compareable nvidia in AC​

nvidia

pros:
able to run 1080p with decent frames and quality
power consumption even less than compareable amd
shadowplay (hardware encoded videorecording and in near future streaming)
more fps in AC than compareable amd card

cons:
more expansive than a compareable amd card
2gb vram
performance weaker on higher resolutions
​

At the moment you can stick with that card where you feel better.
Both manufactors are equal with some slightly more benefits in some spots.

I'm at the moment in the same situation like you, but I'm thinking about 780gtx or 290 (only when custom designs are released).
Nice Cards:

HIS r9 280x (at the moment the silenced one and has good OC potential)
or
evga, palit, msi or asus nvidia 770 oc​

Then your card isn't ok.
I tested AC with a MSi 7970 LBE with full details and 4xaf 4xaa with stable 100fps on 1080p.
By the way you should always turn vsync off because this reduces the Inputlag...
And more FPS or more details is always more GPU usage, when you don't have full GPU usage there are normally two options

cpu bottlenecks the gpu
game settings are not high enough​

 

The fact is, Assetto Corsa is designed to work better with Nvidia GPUs, as rFactor 2 is, that's why I suggested to go with Nvidia...
By the way, if vsync is on I will never have full GPU usage cause there's a limit of 60 fps but for some strange reason with vsync on even though I'm getting less than 60fps my GPU usage is not full. If I turn off vsync then I get more fps and GPU usage is at 98% so I don't think it's my CPU that bottlenecks my GPU, I think it's the game designed that way...
