Effect of a 4Gb card on a 32 bit Win7 system

Recommended Posts

Hi all

 

I have a HD7850 2 Gb card at the moment running on a 6 year old AMD dual core (3.1 Mhz) chip and a Gigabyte Mobo.

 

I have been running GenX! photoscenery with no autogen and the HD7850 copes Ok with that, except I have never been able to overcome the Vsync tearing despite trying all manner of 3rd party software to clamp the rendering.

 

I have started to run OrbX! scenery and the FPS is much reduced, so thought to change cards to a GTX 970 in the hope of no hideous Vsync issues, better shading and lighting, lower power use, cooler, and better FPS.

 

I can't afford a new chip/Mobo combination and only have the Win 7 32 bit OS with 4 Gb of RAM (3Gb addressable with the 'switch').

 

My question please:

 

How would a 970 4 Gb card interact and cope with the memory limitation of my system and should I stick to a 2 Gb card?

 

What thoughts have you generally on my plan?

 

Many thanks,

 

Phil

It's pretty well known that nVidia works much better with FSX than AMD. Even a GTX560Ti would be better off.

 

Ideally though, that PC is old and slow, a whole new PC with Intel and nVidia would be the best option.

I agree with VeryBumpy! Putting a 970 into your existing system is almost certainly a waste of money as you're probably bottlenecked by your CPU and won't see the benefit of the better graphics card. Until recently I was successfully running FSX with Orbx scenery on a GTX 275 which had only 896MB and was less capable than your existing card. The CPU is king in FSX and that's almost certainly your problem.

Many thanks guys, I will instead look at a new Intel CPU/Mobo combination and then look to add a NVidia card upgrade.
