Okay so i have just built a computer last week and i installed a Radeon 4870 in it. Well my motherboard has a Radeon 4200 Onboard graphic. So i am thinking should i refund my 4870 and waiting about 2-3 months until the Radeon 6xxx series come out and buy a better graphic card and it will cheaper by then. Meanwhile in those 2-3 months i can play the games i play on my 4200 on med settings. So should i refund my 4870 and buy a 20% better card in 2-3 months? is this a good idea?
