I'm asking what is the best GPU option to get with a core I5 2400. I'm looking for a equivalent graphics card that will not bottleneck each other. So balance is what I'm looking for. I don't care about price or branding.
Chinese-branded PSU-shaped boxes are rarely any good, doubly so if they don't even meet bronze requirements. You may want to upgrade to something of decent quality before throwing any money at the rest of your system.
