Thanx guys! I'm now the proud owner of an ASUS P5Q Pro Turbo.
Question to RJR: why do I need better cooling? I've already got a nice Zalman heatsink, (with Arctic Silver) and an Xclio Windtunnel case (too lazy to look up the model) and am only at a max of 56c after runnning Prime95 for 12hrs oc'd at 3.3. This flaky 780i runs hot too.... Before my board started flaking out I was stable at 3.5 with the same temps.
EDIT: d'oh! just re-read your reply, RJR. You meant a board with better cooling. Thanks for the suggestion, it will be nice to have a board with rear USB ports that actually work. Every rear USB port on the 780i no worky.
