I really hate people that do this.
"I need something that's the best thing ever, but I dont wanna pay anything.." It's like that time somebody asked me if there was a 4k gaming rig that was $500 or less. It's just facepalm worthy.
Short answer, no. If you want a GPU that will even do anything serious, you better drop the cash for one, or don't get one at all. You can't have your CPU and eat it too.
