Right now im rocking a i5 3450 16gb of ram and a rx470 8gb OC. Now i want to increase my fps while being able to do some video editing and streaming . I have a $300 budget and i can get a ryzen 5 2600 with some cheap am4 mobo and 8g of ram on amazon for $299. So should i buy this cpu another cpu or save up for a new graphics card thanks!
