i got myself the MSI Z77a-G45 for 100$ with a 20$ Mail-in (so 120$ at buy time)
Dark Brown PCB (like all MSI line) Oc really well (wasn't expecting 105 baseclock and 4.83ghz for a cheap board like that but it run for 1 year now withtout any bugs) Blue accentued cooler that looks awesome, SLI, Crossfire and RAID like most 150-160$ board (not like the g43 or g41 that aren't SLI compatible but cheaper)
well that's it !! for a 100$ board, i can't find a better value !!
PS: Gigabyte make fantastic board too, i'm still running a P45 Gigabyte board with a Core 2 quad Q6600 OC to 4.05ghz (450*9) with 1200Mhz ram, running flawlessly from 2007-2008 to now !! That's the best motherboard i had as i pass two ASUS Rampage Formula on the same Q6600 (both failed on me killing the gpu both time and they send me a new one but not pay for the GPU so i simply resell the 3rd board as i don't want to toast another GPU in there...)
I also had a P4P800E-DLX that failed on me with a P4 3.4Ghz SL8K4 OC to 4.35Ghz with ddr400 OC to 512mhz...
I'm not trusting ASUS anymore, i expect my soundcard to broke someday (sad but i really think that, too much badluck with them...)
i also build a "cheap" lan party rig for a friend with the Z77a-G43 (no SLI and no OC headroom as Vcore is limited by the bios but only 80$) but his I5-3570k still manage 4.6GHZ paired with a 660ti, fantastic and cheap rig
