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.
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.
But since you're here, no, that PSU isn't great unless its just 4850s you're CF. There's only 2 PCIe 6/8 connections, and you'll need four for a 4870+ CF setup.
Look for something with 4x PCIe connections. The corsair 750tx is a decent choice.
The 790FX will give the best CF performance, but a 790GX should do well too. Just make sure there are in fact 2x PCIe x16 slots on the board. If your looking at the 5850 too, I'd wait till an evaluation review hits to see if the 790gx bottlenecks the CF setup or not.
