I have a 2005 dell xps 600 with a foxconn Ls-36 motherboard, ddr2 ram. Does that mean i gotta have a graphics card ddr2 also? I thought ddr2 was the connection type on my motherboard...idk. lol. ddr2 graphic cards are harder to find.
When your dealing with cards that old, it kind of doesn't matter.
No idea on those cards, but make sure that your actually getting an upgrade here. Your essentially upgrading a top tier card of one generation for the low-mid range card 2-3 gens later.
