Hello, I'm a first time builder and my graphics card I have now is old. Maybe 7 years it is an AMD RADEON 5450 ATI and I think it's getting wore out. I used to get like 70-80 avg frames on CSGO now I have like 40-50. My processor is AMD ATHLON 5350 will buying an Gigabyte Radeon RX 460 OC 2GB cap my frames or better them? I would love to have a fast response as I am looking to ask for this for my birthday PS: This computer is built to play CSGO and Minecraft not really looking to play any heavy games besides GTA IV (Which isn't really that heavy)
