I want to buy a new graphics card, ASAP. I have the HD 4870 in mind, because its cheap and powerful. The HD 4890 (the rumoured card that might be released in (+-)3 weeks) will be in the same price range and with more power.
What must I do? Wait for the HD 4890, or won't it be worth it. And if I should wait, how long should I wait? Example: until all the driver issues are fixed; until a review/benchmark etc..
