GPU support

Hello everyone! I have Geforce GTS 250 and GT 630 for now, which one will be better unreal engine realtime preview ? I use engine for animation . Thanks in advance

they are both pretty bad but id say the 250 may win out at least according to gpuboss. of course the best thing to do would be to make a scene or whatever your trying to do then render it out and see which one is better. basically take them for a test drive.
