Hi!

 

Using an i5 2500K oc'd to 4500Mhz and a Nvidia 570 GTX (1300 MB) I wonder which video card might give me the best performance without upgrading the CPU.

I'm only using a single monitor @1920x1080 and use all kinds of aircraft (P3D).

Do I need (or profit from) more than 3 GB VRAM?

Is ATI an option?

 

Thanks for advise!

I have a 2500k OC to 4.8GHz and I went from a 580 GTX 2GB (I would say similar to your 570) to a GTX 670 2GB and I was very pleased with the results and I was using 3 27" 1920x1080.  One display ran great.  So in that prerformance/price range I was getting good results and I assume you would have the same.  I did just upgrade to a EVGA GTX 780 6GB as I wanted the extra VRAM for the three displays and I can see I now have more headroom to play with my settings.  When SLI is ready for P3D I will pick up a 2nd card and I should be good to go for quite some time.

 

Hope this info was helpful

Thanks for your help!

 

Your old 580 had the advantage of having almost double the RAM of my 570. Mine is always on the edge and this gets noticeable with blurry textures which talke forever to load (overal fps are fine though)

 

So, comparing various benchmarks and prices I came to the conclusion that a 4 gig card would be a good idea (also but not only for flight simulation). Depending on the actual time opf purchase, a GTX 770 or a custom designed R9 290 came to my mind.The latter being more expensive but with new ATI cards announced it is fair to assume a price drop in the coming months.
