If you trust Asrock, stay with it, otherwise I suggest moving to Gigabyte or Asus.
I don't personally trust Asrock, but that's just because I've gotten DOA boards from them in the past and their tech support was not very helpful.
I got run through hoops until I gave up.

Also if you do/do not absolutely want to go with Intel for your build, this is a very solid build with similar specs to yours, but going with AMD and the Phenom II X2 550 for only a little over $400
Thus letting you invest the leftover money in graphics.
Perhaps a 4850 if you want to squeeze a $100 graphics card in there now? Or you can save and wait until later.
Also, there's the possibility of being able to unlock that Phenom II X2 550 to a Phenom II X4 B50 Quad Core.
If it unlocks it may outperform the i3 530, if it doesn't unlock the i3 530 will outperform it. However, Going with the AMD build saves you $100 for similar performance and having the AM3 socket will enable you to have the upgrade path for the Phenom II X6 (Six core Phenom's) In the future, as AMD has stated they will be compatible with existing AM3 motherboards.
Also the Asus 780L in this build has integrated graphics (That are about as good or possibly better than the integrated graphics with the Intel build you made) in case you would still want to hold off on buying a graphics card.
Just something to consider AMD vs Intel for a budget build. It's a tough call.
