Still need help deciding on:

With about $400 left in budget I need to pick up a Mobo and GPU.

Motherboard. Xfire capability would be nice, but not sure if my 550W PSU (which I already bought) could handle it, and it will probably push me over budget. The most important factor would be overclocking stability and quality of materials (don't care about those automatic overclocking gimmicks)

GPU. Leaning toward the 5850. Zipzoomfly had the XFX HD5850 for 269.99 just a few minutes ago for preorder. And now it's 299.99 and says out of stock!

Thats about it. Feel free to critique my build, suggest combos, or anything. Saving a few bucks is always nice! (As long as there's not too much performance compromise) I was thinking of maybe changing to a cheaper case or something, or shaving a few bucks off the RAM.

For the motherboard, if you buy from a famous company like MSI, Gigabyte, ASUS, but if you buy a cheaper version, does it mean the overclock Quality isn't as good?

The OC ability has more to do with the chipset followed by the quality of components on the mobo itself. If you get an Asus or Gigabyte, even the entry models, you'll have a good OC board. Since you've locked yourself into a single GPU solution without a PSU upgrade, you can pick one that only has 1x pcie 2.0 x16 slot. That will be the boards around $100, so you can still get your 5850 and stay well under the $1k mark.

Thanks!

This is kind of a thread hijack, but if I had something with similar specs and wanted crossfire in the future, what would be a good mobo around $150 to purchase?

Also, is this PSU good enough for Xfire? http://www.zipzoomfly.com/jsp/Prod [...] t=celebros

So my 550W will definitely not suppoort crossfire? haha. How much power do you need for it?
