lets first say that this is a great card for the money.
so lets get to it with this card. it is a great card for all your multimedia needs featuring a duel DVI ports also with the pack you receive all the normal adapters DVI to VGA ect but it also comes with a DVI to HDMI adapter great for watching and playing on your big screen tv. this has 256Mb of GDDR3 memory. GDDR3 is faster than GDDR2 and therefore is better for all applications. when playing games it keeps up and is surprisingly good, ok it won't beat a GTX but it's great for the money. i gets around 40-57 frames on the newest games like Call of Duty 4 & 5.
as with all Geforce Units it features plug and play as long as your previous card was a Geforce
this card does require more power than just the PCI express so you will need a a PSU with a 6 pin connector or 2 molexs for the adapter supplied
all in all i would put this well above the ATI range of the same price due to its GDDR3 memory
