HD2900XT is an old and power hungry card that would never run on your std power supply. You did not specify what form factor it is but it was available as a slimline as well. If it is the mini tower then cards like HD4650/70 would be the best recommended upgrades.

an 8800gt , 8600gt , 9500gt , 9600gt , 9800gt
u have to upgrade psu for 8800gt or 9800gt

8600gt is a good choice

Both rolli59 and IROC_69 make good points. Unless you plan to upgrade your PSU as well, you need to stick to a GPU that will not require external power, nor draw too heavily on the stock PSU. I would recommend you look at the HD4550, HD4650, HD4670, or HD5450. They may all state that they recommend a 300W or better PSU, but they work just fine in Dell's with their 250W PSUs. Good luck!
