[laptop-]

Hi all I have this old computer I was gonna scrap some parts from and I was wondering what's the highest end graphics card I can run with this processor without bottlenecks occurring it's the AMD Athlon 64 X2 Dual Core 4200+

depends on your screen resolution

but anything stronger than a Radeon 265 or GTX 750ti will be wasted

I'd be running at 900p
