In over my head choosing mobo... help?

Planing a build - doing good not pestering anyone about choosing most parts...but mobo's is getting the best of me, am lost.

Heres what I have in wish list so far:

- Intel Core 2 Quad Q9550 Yorkfield 2.83GHz LGA 775 95W
- MSI R4870-T2D512 OC Radeon HD 4870
- OCZ Reaper HPC Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit
(... maybe X 2...its cheap )

I still have to look at power supply and CPU fan, will put in best bang/buck 750gb harddrive I can find and throw all that in Antec 900 case (tho that is flexible)

I don't plan to go crossfire in near future but would like to keep option open. Plan to do more gaming than is responsible but don't do any graphic or video editing. Care about best possible sound quality but don't need 7.1... I mostly use good headphones (may get soundcard in future but not yet) Not comfortable trying to OC so don't really care about potential for that

Yeah, that's about it: music & gaming is what I am looking for so prefer not to be paying for bunch of features I won't need/use... thats whats confusing me. I expect to pay around 150-200$ (but of course cheaper=better) So would very much appreciate suggestions from such knowledgeable folks as you guys or link to good recent buyers guide (only finding dated ones )

Many thanks

Yeah I just did a search by rating on newegg and a lot of DFI comes up in first page and in price range...I have mostly read about ASUS & Gigabyte but DFI is good to?

I personally wouldn't use the Asrock. If you're looking to save money by going with a P45 and willing to take just a bit less performance for crossfired HD4870s, i'd go with an Asus P45 motherboard. It also comes with a nice combo deal for an Asus HD4870 GPU. Dropping it to $205 after rebate.
