I think the price is too high, its an excellent board but its still a socket 775 board using DDR2 for upwards near $200, and its used. There's one on eBay right now for roughly the same price buy-it-now, refurbished.
Is your P35 limiting you from overclocking your E8400 higher? Do you plan on adding another 4890? I don't see what other advantages there would be to upgrading the motherboard.
dang. i do plan on going CF eventually. im just itching to upgrade my old gigabyte board and love the asus boards. i cant find a good asus board for less than 200 that has CF besides the maximus 2 board. i dont think the guy will go any lower and im suppose to pick it up tomorrow. should i shoot for asking about 160? maybe less? could ya'll give me some sights to look on to get a board around 150 used/new like an asus rampage maybe
I suggest you pass on that board for a better deal, they are out there. You're going to want something with a x38, p45, or x48 in it to do CF, shouldn't be hard at all to find one under $150. I picked up an x38-based Maximus Formula with the stock northbridge waterblock for a little over $100 last January. I'd personally hold off upgrading the motherboard until I had a second video card. Also, Gigabyte makes some great x38 and p45 boards in addition to ASUS.
I had a Maximus II Formula, and loved it. But I wouldn't say $180 is a good deal. I paid $150 for mine used about a year ago, and sold it for I think $125 a few months ago. The best thing about the MIIF though, is it is probably one of the best looking motherboards around (same with the Rampage II Extreme, which I've used as well ). Nothing like looking into your computer and seeing that in there. The x48 boards just don't have the same look.
