your answer was cool
LOL Thanks I guess?
Short and simple answer though, is no. The old Pentium D series is not suitable for the latest generation of graphics cards. The new nVidia GTX 4xx series, and ATI 5xxx series cards would suffer fairly dramatic performance loss.
If you're looking for a graphics upgrade, you might provide more information about what games you want to play, what resolution you monitor handles, etc. Folks can suggest what works with your system. Otherwise, it's probably time for a system upgrade if you want to do serious PC gaming.
