^ overheating issues. which of course could be overcome by better cooling which requires 'more money'. Otherwise its my choice too, well the one that comes first with looks and spec wise.
Both this and my suggested have no usb3.0. So in short, i would recommend you to stay with your current board. don't think until new mobo's arrive. Try some push/pull configurations and better the cooling.
Ummm but if I use 16x,8x config ... I'll loose some "power" no ?
On ud3r I think I could use 16x,8x also (and solve my heat prob), I pay for 2 "big" video card I 'didn't loose anything
You are likely to only see about a ~1% drop in frame rate. There isn't that much of a difference between 16x,16x vs 16x,8x. Tom's has done quite a few articles and only found a real difference at 16x,4x or 8x,4x. You shouldn't be able to see the difference in this board vs one with 16x, 16x.
