Hihi, got a Gefore 8800 xfx today, and I'm 99% sure my computer is underpowered to use a card like this properly.
I know that for graphics cards it's a matter of uninstalling drivers and then dropping the new card into the old one's slot , however for power supplies is it basically the same thing? Do I need to do anything else? Like is there a chance it won't fit in the same area as my last power supply if I get another one?
I have a strong feeling my power supply is only around the 300w region (never checked!) and will upgrade to 500w If it's not high enough.
