i just bought an ASRock 870 EXTREME3 for 89.99 on newegg. doesn't seem like you need a mobo with HDMI when you're already getting a graphics card. anyway, i bought the AMD 965 on newegg combo deal with an XFX Radeon HD 5770 for 224.98 after MIR. i'd also go with g.skill for RAM.
^+1 And if you feel like splurging, you could add a 60-80GB SSD for boot. That's gonna cost you in the area of $150 though. If you're interested we can give you some good models.
