Seriously a bad time to buy graphics card.
DX10 cards are around the corner already (June/July)
If you're on AGP, no point to upgrade to a higher spec card unless your system/CPU can take it overall. Performance gain is usually marginal.
If need to - go full out PCIe. Bear in mind, some cards require an additional power supply molex to be fed directly from your PSU - so having a quality PSU and capable PSU is another factor as graphics cards are power hungry buggers.
