However I am unable to decide on a motherboard as of yet. I need it to be able to crossfire later on when I can buy another 6800 series card. Also the motherboard should be stable enough to overclock the 2500k to respectable levels.
I am also gonna put in my sound blaster card in one of the slots. Would that be an issue when I try to go for crossfire?
The PSU / casing / hdd will be used from my existing PC so no need to purchase them at this point of time.
but frankly I am at a loss to compare the motherboards, most of the features are almost similar. My biggest issue was to find a board with good over-clocking capabilities for future with crossfire support.
I am based in Singapore so parts availability should not a issue.
Any advice will be much appreciated.
In general, I only recommend ASUS and Gigabyte boards as they are just above and beyond everyone else. It seems right now that ASUS is the leader in z68 boards. They just seem to do it a bit better than Gigabyte. That ASUS board in particular is a very good one and should serve you well.
You can certainly do a sound card, although the onboard audio is quite good these days.
