I haven't been following hardware for a few years. Will this work with my motherboard, power supplies and Windows XP SP3 (Direct X).
Yup. Your PSU has the 6-pin it needs, the 7750 sips power so there shouldn't be a problem with amperage, and everything else is backwards compatible. Just note you're not going to be playing any DX10- or DX11-only titles on a DX9 OS. (Which shouldn't be a problem.)
Thank you for your help. I would love to get a better card but it is hard justifying putting a lot of money into this rig when I've got the itch to get another machine. Windows XP quits getting updated next year so this rig will get either Win7 or 8 installed. The card also runs at 900MHz so it should be a little closer to the 7770 that has been recommended.It'll work, and it's a fine card for ~$50. A 7770 is obviously going to be faster, but you get what you pay for.
