My PC right now has:
i5 11400f
16GB DDR4
1TB SATA SSD
256GB NVME
GTX 1650 Super

I just wanna know what is the best GPU that is small, efficient but still powerful is because my case is small and my PSU is only like 400-500W (i cant swap it cause its a proprietary case so proprietary PSU) I need a GPU that is roughly the same size as a GTX 1650S and it needs to be around £200

Thank you!
