|Win XP only supports up to DX9. Besides, the cheapest DX11 card isn't going to be a gaming card & since you're posting in the gaming forum, I assume you want to be able to play games? Also, DX11 cards are PCI-express only, so you'll need to make sure your motherboard has a PCI-express slot. You also need more RAM. 510MB isn't nearly enough these days.|
Post your system specs & which games you want to be able to play.
