If the 4870 has double the memory as the 4850 is it worth paying $30 extra dollars? And when do you think I'll have to upgrade my card again? I'm just a casual gamer playing CS:S and TF2. Thanks for your time!
i'd recommend getting a 5770 though, cheapest one on newegg is $135 after rebate, cheapest 1gb 4870 also being $135, so i think the 5770 will be a better deal, it'll give you same penformance as the 4870, but with dx11 and lower power consumption
