Rosewill RX850-D-B -- good solution?

Newegg has a pretty nice one day sale today on the Rosewill RX850-D-B:

Thats $100 instant savings, free shipping, and apparently a free case, although I can't imagine the case is any good.

The review I read here: http://www.jonnyguru.com/modules.p [...] y4&reid=60 is generally positive, although it cautions that it's mainly designed for systems that use the 12V rails heavily and warns that it doesn't have 8 pin pci-e.

The problem is that I have no idea if the build I am planning needs 8 pin pci-e or relies on 12v rails.

My basic plan is to build a gaming PC with at least a modest OC, based around an i7 920 and some mid to mid-high range graphics power. Was considering running two 4770s in crossfire, but I might go a bit higher end than that with a single card build now and expand to a two card build at some point in the future when the prices go down.

8 pin PCIe is based on the Video card. An example is this: 8800GTX. Most newer video cards , even the high end ones, only use 2 x 6 pin PCIe now.

So unless you plan on using something older like 8800GTX, 9800GX2 or HD3870x2, i wouldn't worry about it.
