Suggestions for New System?

Greetings:

My current system is turning 5 years old this month. In an effort to celebrate this momentous occasion, I am building it a new friend. I plan to use the new system for gaming, graphic design / image manipulation, virtualization and general office application functionality. I would greatly appreciate any advice or suggestions regarding the following components:

In the near future I plan to purchase a second Radeon HD 4870 and an additional 4 GB of RAM.

Thanks for your advice!!!

Thanks for the reply!

I am now planning to go with a Radeon HD 4870 X2 instead of the non X2 4870 model mentioned in my original post. Will a 850W PSU still allow me to crossfire two 4870 X2s together?

Does anyone have a preference when it comes to manufacturers of 4870 X2s?

I am looking at either the

DIAMOND 4870X2PE52G Radeon HD 4870 X2 2GB 512-bit (256-Bit x 2) GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Prod [...] 6814103066

or

ASUS EAH4870X2/HTDI/2G Radeon HD 4870 X2 2GB 512-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
http://www.newegg.com/Product/Prod [...] 6814121269

The DIAMOND brand is cheaper ($499.99 after a $50.00 Mail-In Rebate). Is there any other reason to go with one or the other?
