I just read an article stating that to use a 3rd monitor you need a special hdmi converter cable with the HD 5850. Has anyone worked with 3 monitors and if so what cable did you get and where. Will the 5850 card work if the center and side monitors are set to 2 different resolutions namely 1280*1024 for the side and 1900 by 1080 for the center.

For your thermal compound I'd recommend Arctic Silver 5.

I recommend buying this combo, since you don't list a hard drive...

Western Digital Caviar Black 640GB Hard Drive & COOLER MASTER RC-690 Case

Memory: I'm a fan of the G.SKILL Ripjaws Series 4GB (2 x 2GB) DDR3 1333, since they have tight timings and lower voltage.

I'm good with the CPU cooler...

On your graphics card: If you can't get XFX card, I would get either a Sapphire or HIS card... IMO.

newegg lists items not to be in stock for a while as deactivated

The Ripjaws memory is rated at V1.5. Most other memory seems to be around 1.7. Will this be a problem if I want to OC?

Thanks everyone for the replies.

Waiting for the cards to become available and decide what to do if I want to try multiple screens.

Can anyone recommend an active displayport connector if I decide to try 3 monitors.

Do all 3 monitors have to have the exact same resolution? or can say the widths be different if the heights are the same?
