Upgrade Geforce 9600 GT to Radeon HD 6850

[co0ldown]

Hello, i'm thinking about upgrading my old Geforce 9600 GT 512MB to a Radeon HD 6850 1GB. But i have no idea if my computer's parts can handle it.

I got a Fujitsu Siemens AMILO desktop Pi 3630 that i got like 4 years ago.

All the specs are here, http://www.dooyoo.co.uk/pc-desktops/fujitsu-siemens-amilo-desktop-pi-3630/details/

I really hope you can help me.

It should fit, however I think you might want to upgrade your psu.

Yea, i was thinking about that aswell, is it hard to "install" ?

As long as it doesn't happen to have some sort of goofy proprietary PSU, it should be a piece of cake. The case looks large enough where you shouldn't have to worry about how big it is, unlike some HP cases that I've worked with. :\

Allright, But i'm abit worried about the cooling.. it is very dusty at the PSU and it is very hard to take it apart, and sometimes when i've had it on for like 5 hours straight it can sometimes run for 5 seconds then stop, then start running again then stop (the fan).

And, according to Speedfan, my GPU says 59°C.
