Yeah haven't done much upgrading lately before the big upgrade to AM3.
Just an Accelero Twin Turbo for the HD4850 and a WD 1TB Black.
I have posted a thread about the unknown dramas installing the cooler.
Ranging from modifying one VRM a little, poor thermal tape and having to edit the original BIOS with RBE to make the fans work without software.
The original HD4850 BIOS made the fan run passive until 70degC!
Temperature dropped from 96-110degC max to 54-55degC max.
The cartoon like Republic Heros of all games made the card reach 110degC -_-.
If you're bored, and want to mod, see if the Thremalright Spitfire fits your card LOL!
You already have a monster CPU cooler with a heatsink for the CPU's backside, your rig would look sick with a monster VGA cooler.
