[Sxmdy]

My spec Processor AMD A8-6600K, Motherboard Biostar Hi-Fi A85S3 and i'm trying to search a new VGA, my old VGA GTX 650.
Im trying to searching some VGA before I write this, I found GTX 950 and 1050, any advice for great VGA to not make my pc bottleneck? please reply.

Sorry for my english, i'm bad at grammar.

1050 is slot powered so should be fine.
