I would seriously have a look at your PSU to make sure an 8800GT will run on it! It needs 24Amps and a lot of people dont realise their PSU does not output that much, never mind 450Watts! It depends what you want the card for and the spec of the PC its going into. There is a massive difference between the 8600GTS and the 8800GT and the GT is worth the extra £20 if your system runs it.
