In my opinion and from personal experience Biostar motherboards are not that dependable, a couple years back i built a P4 machine with the 775 socket, back when P4 was in its prime and used a Biostar board, nothing but problems with it and customer service. the first board was the capacitors then the next board which newegg replaced cause it was in the 30 day period, it went through power supplies like they weren't even there!
So my suggestion is that you look for ASUS, Gigabyte, EVGA, FOXCONN motherboard, they have been the boards that have worked for me.
And on the video card i wasn't sure about the 5 series video card because i was planning on building a new computer or upgrading my current one and was going to go with a similar card as you and was told that it wasn't worth the money because it would just consume more power then i would get in performance. But was told the 4670 was a great card for gaming+.
Quad-cores are just as good with gaming, i myself am using a Phenom quad core and it runs just fine with all the games i play, and i play some old and the newest of new games. the only problem i have with it is that no matter what i throw at it, it doesn't seem to want to go over 85% usage and thats with video editing playing a game in another monitor and listening to music with the visualizer on(forgot that it was on till i looked at the other monitor, normally never use a visualizer!
Also Antec power supplies do not suck, i've been using the same one for almost two years now and never had a problem, but going to upgrade to a 600w PSU soon when i get another video card and hard drive!
Good Luck with your Build!
