take your pick, all those sub GBP100 mobos are pretty good. but based on the pics i'm seeing, the only reason anyone may have a problem with MSI's G45 is the no. of chokes the board's carrying, but for the price that should be expected. and seeing as you're not OCing, not with the 4570, that argument's moot.
on a more bias perspective, most of my personal acquaintances has a lot of negative things to say about MSI's quality and service in the last 2-3 years. but that's me, your mileage may vary.
