Bought the card for a computer only 3yrs old but starting to lag a bit over graphics and displaying BBC iplayer at full screen was impossible to watch, graphics were onboard (attached to motherboard). This card has vastly increased the speed of the games I have (not modern games) and can now watch iplayer at full screen and no pixel dancing or freezing up on me.
This card thou is not suitable if youre a serious gamer me thinks, even set up in crossfire with 2 of them. To play Modern warfare for example, be time the card has processed the data and refreshed the screen, you'd have been shot 2sec ago. But to bring a older PC back to life, for a new build PC where youre not interested in high end games, or for a Media PC with the low profile bracket its Perfect and with HDMI,DVI and D-sub(VGA) connectors so whatever monitor you have, it will work.
For the PC connection inside the computer, as long as you have a PCI-E 16x connector it should work, whether its PCI-E 16x or
PCI-E 16x 1.1 or class 2.0, They are all backwards compatable and future compatable.
