lol okay i was just asking to see if you would need a new power supply as well. That would add to the cost, any recommendations would be limited by your power supply. If you only said the wattage then I take it is not a good branded one?
Battlefield is really demanding. Minimum is DirectX 10 or 11 compatible Nvidia or AMD ATI card, ATI Radeon 3870 or higher, Nvidia GeForce 8800 GT or higher.
You could get something like a HD 5770 which is good value introduction to "gaming cards" but you will have to lower the graphics setting in battlefield to med-high depending on your resolution.
Whether a 500W or 550W PSU with one PCI-E 6-pin connector from the PSU will support 6770 and it's probably the cheapest card for BF3 and will have very small chance of having insufficient PSU. Here:
for gpu your gt 210 will play bf3 with low settings and lagsits an weakergpu no need to buy that you should go higher to hd 6xxx series graphics atleast hd 6850 for bf3 it can play bf3 without lag with high settings with none aa at 30-40 fps thats good enough.
