all in your budget. for the xfx card this is the model no. pvt-43k-ndf7 ... u can also go for the 256 mb version of the same card provided its in your budget.
intel original 865 gbf available rarely now... in that case go for the asus p4p-800-vm (865 chipset) or p4c-800e- deluxe (875p chipset) .. asus mobos will be expensive though. and ya if u have some extra cash buy another 256 mb ram module from the same company and run in dual channel.
